External Midi Events Playing Too Early

Hi there. Got a bit of an issue with midi timing under Logic 8, I run an Emagic AMT8 and a MTP AV as my midi interfaces but I'm noticing the midi events are playing before audio events, ie if I've got a bassline running on an plugin instrument, copy it to an external midi track and trigger a midi synth the synth is playing back earlier than plugin by about -120 ticks or whatever the delay compensation unit is in the inspector. This is global across all midi ports. I've got full plugin delay compensation turned on for the audio, my buffer is 512 (I use 2 UAD cards and thats the recommended setting)
I've hunted high and low through the manuals but can't find any parameter or reason why this would globally apply across all external midi ports, any suggestions greatfully appreciated as its driving me nuts.

Well Logic's Plug In Delay Compensation only works for the native Plug Ins not for external Midi stuff so the best thing to do is to record your external Midi as Audio data and align it with the rest of the music otherwise you'll get grey hair trying to find the correct delay offset to sync your external Midi.

Alignment of external MIDI events and audio

Hi,
I've been doing some careful measurements of the timing of MIDI events under Logic 8.0.2. I record a lot of external MIDI hardware, so the timing of external MIDI events and its relation to recorded audio is very important to me.
My setup is OS X 10.5.5, Logic 8.0.2., all relevant patches and updates. I'm using an RME fireface 800 as both the audio and MIDI interface in these examples.
I've created a project in which there is no plug-in of any kind: neither instrument nor effect. Even the klopgeist is gone.
My preferences settings:
Audio/Devices:
buffer=1024 samples
sw monitoring=off
indep mon level=off
I/O safety buffer=off
Audio/General:
PDC=Off (I also measured with PDC=all, to verify that it has no effect)
low latency mode=off
I create an external MIDI track of quantized whole notes: C3, playing on the first tick of each bar. BPM is 120.
I then create another external MIDI track, cable MIDI OUT to MIDI IN on the Fireface, and record the first MIDI track onto the second (i.e., loopback test). The note data is right on the money; within one tick of the original values. I set PDC to all, repeat the test, same result.
I then cable MIDI out on the Fireface to a hardware synth, and call up a patch with a sharp attack. I route the audio output of the synth to an audio input of the Fireface. I create an audio track with this input selected, and record the output of the synth. The recorded audio is early by 20ms or so -- roughly equivalent to the buffer size.
I repeat the test with PDC set to All, same result. PDC has no effect, as you would expect, as there are no plug-ins in this project.
I then set Preferences/MIDI/Sync/All MIDI Output delay to 21ms. I repeat the audio recording test, and now the recorded events are on the money.
Here are my questions. First, am I doing something wrong, or does Logic have a fundamental bug concerning the linkage between MIDI timing and audio timing?
It seems clear to me that this timing error has nothing to do with PDC. There is no "P". Right?
I thought that the RME has timestamped MIDI. The RME manual speaks of very accurate MIDI timing, and I can verify that the MIDI jitter of the Fireface is indeed low, in the 1ms neighborhood. This is borne out by the MIDI loopback test I did above. But MIDI timestamps don't mean anything if they are not correlated to the time code of the audio, haha! What am I missing here?
If timestamping the MIDI data can't work for some reason, could this problem not be solved by having Logic automatically delay the transmission of external MIDI data by an amount equal to the audio buffer size? Put differently, my solution to this problem is to set a MIDI output delay in preferences equal to the audio buffer size, i.e., 21.3ms. And this seems to work. Is that a proper solution, and if so, why does Logic not do such a thing automatically?
Thanks,
-Luddy

OK, so I just retested and here is the best part... I recorded a loop from my drum machine, cut the first note nicely to the 1 on the first bar... using a count in etc.
I played it back and looped outs 3-4 back into 1-2 on my Ensemble. I also played back the same kick on my drum machine just to check this reverse latency issue. I was not concerned with hit for hit layering accuracy. What I got back astounds me!
The "loopback" recording was spot on to the original being played out... totally locked. BUT, the one that was midi clocked by Logic and play from my drum machine came in ahead of the 1??? How is this possible when I am hearing it when monitoring this recording and it is slightly behind? RIDICULOUS! What does this mean?
Logic is NOT recording what I am hearing, but rather recording some timewarped version of it in which it places events ahead of when they happened, but ONLY on midi clocked or midi sent notes!
I have lurked here a long time and I know that there is not much known here about this issue, so before anyone tells me the typical solution I will say as I did in my last post:
I have done a ton of tests like this, I also followed the loopback testing as described on Logicprohelp.com.
Yes I tried it with all PDC modes, SW monitoring on AND off.
I am truly beginning to think that this is a major bug of some sort.
Anyone else out there with hardware that reports latency to Logic (RME, Metric Halo, and Apogee stuff are ones I know that do this) experiencing this abberation?
thanks

HELP! External MIDI is playing EARLY compared to the audio tracks!

Hi Guys
I have a project in L9 which has about 12 audio tracks, each running a few effects (fairly basic ones, nothing too heavy).
Tonight I am recording a rhythm part on an external MIDI device (my Kurzweil synth). I'm quantising this part to 1/8 notes, and in the piano roll editor, it's lining up perfectly after quantization.
However, when I play back the project, the MIDI is all EARLY!
I've tried soloing just the MIDI and the click, and the MIDI part runs uniformly early compared to the click track.
I believe this has something to do with the delay compensation that is in effect across all the audio channels... what's happening is that all the audio content is being delayed so all the tracks sync with each other. But for some reason, MIDI is not part of this delay compensation, and is playing in perfect time, and hence sounding early compared to the audio material.
I've done a test new project with just one MIDI track, and when quantized, it DOESN'T suffer this problem... ie, it aligns perfectly with the click track.
Is there any way to get external MIDI instruments to be part of the delay compensation process? Or is there some other solution to this issue?
Really desperate here as this has come out of the blue and I can't think of any way to solve it!
Thanks heaps guys,
Mike

Is this something new for Logic 9?
I don't know, I have never used external MIDI with Logic (8 or 9) - but think it is new, yes.
I wonder if there's a way to set the global default for MIDI so that it always has delay compensation? I can't see why anyone would want to use an external MIDI device and not have it in perfect time with their audio material!
Yes, there is. You'll have to set it up in AMS first (choose *New Device*, and then configure the device and cable it) In Logic, you'll have to go into the Environment. You need a *Standard Instrument Object* for a monotimbral device, a, *Multi-Instrument Object* for multitimbral devices and a *Mapped Instrument object* for Drummodules. Explanation starts on pg 1082 of the LP9 pdf manual.
Once it is all setup, you can make a template of it, or you can import the Environment layer into new projects.

External midi playing too early when quantized

I have a Motu MK2 ultralite... i dont see any option on it. Everything seems fine with logic.. this only happens when i have alot of stuff going on in my session...

PDC must be set as Audio and instrument tracks when tracking
About Latency:
256 buffer and PDC as picture shows when recording...
when Mixing set the buffer at 1024 and the PDC to "All".
If you start recording with PDC set to all and buffer range processing set to ALL the resulting audio recording will be not in sync...
because PDC is an additional Buffer ... it is related with buffer processing...
Large, Medium, Small...
with Small setting you wil get a very litle delay but .... only if you set as i suggested everything will be in sync
if you need additional Sample accuraxy you need to set the *recording Delay compensation*
But this must be done with PDC set to off or Audio siftware instruments...
if you want traching with PDC set to ALL you must use Low latency Mode turn to ON!

How to start midi event playing from the middle of event?

I'm not sure if my post title is correct but...
I have a two minute piece of music with various instruments playing. There are some strings that play the same couple of notes throughout.
At the moment I am working on a middle section but as I loop, the srings aren't triggered - I have to play from the start (before the event starts). I did not have a problem with Cubase but I can't find a way to do this in Logic.
It's probaly quit simple though?

This typically means the midi notes themselves start before the beginning of the loop point you have choosen
You can quantize or manually move the first notes so that they start at the beginning of the loop and not just before... to resolve this..
Select the regions and then check the event list for the region to confirm this is what is going on...

External MIDI recorded as Audio is early

Why is it when I record MIDI data sent from Logic 8.02 to an external synth module and recorded back to Logic as audio is the audio earlier in time than the MIDI?
I played with various delay comp settings and this didn't seem to help.
Many thanks!
Alan Hayes

I have a new Apple dual quad core 2.8Ghz Mac,10 GB RAM, 2TB HD,Apogee Ensemble, Emagic Unitor 8 MKII(USB),Logic Pro 8.02,OSX.5.4.
I am not trying to slave a drum machine or anything else with a clock or any sync messages at all, I am just simply playing back a MIDI sequence from within Logic routed to an external MIDI synth module and recording it back into Logic as audio.
The audio recording is earlier than the MIDI Logic sent out.
This happens with all the MIDI external synths and drum machines I have treid not just this particular unit.
I played with buffer settings, no difference,I turned on and off plugin delay compensation,no difference,BTW this is with a brand new song not made from any template, only one audio track and only one MIDI track, I played with recording delay and got close with a delay of 118 and the audio on beat 1 would be late then on 2,3,4,5,6,7,8,9,10.......it would be early, then on bar 25,26 it was right on time and then it started to get later for every consecutive beat.
Since Apple removed the ability to sync to an external MIDI clock in version 8, now I have to send my clients a MIDI clock and record their data and send it back via MIDI to their workstations or drum machines and now it won't record in time?
I have worked with Logic since ATARI 1040STe back in the late 80s and it was always rock solid in the realm of MIDI from whence it came.
Is there a solution to this I have overlooked?

Import midi and play to external midi

When I import a mid(i) file, it creates all the tracks and plays back through the system output. What I would like to do is play it to my USB attached external midi device.
I can do this by moving individually each track to a newly created External Midi type track but was hoping for an easier/faster way.

Can Garage Band play an external MIDI synth?

Can Garage Band play an external MIDI keyboard?
I have an external MIDI keyboard/synth.
In Garage Band Preferences I’ve set Input Device and Output Device to my external MIDI keyboard.
I can play the external keyboard with Garage Band in Record mode and it records just fine.
However, when I select Garage Band to play, nothing plays on the external keyboard.
I can set the Output Device to Build-In Output and Garage Band plays the software synth on my computer just fine.

Thanks lenoie
What I'm hoping for is for Garage Band to send MIDI out to the external keyboard.
Does anyone know if Garage Band can do this?
Thanks :-)

Logic Pro 10.1.0 update. automation and external midi tracks issues

Hi there,
After i i installed the update I am having some issues with transferring automation to region/track and viceversa + othe issues in creating GM external midi tracks...
anybody else experiencing the same?
Marco

Yes, that behavior is really odd indeed. Never experienced that and never heard of it.
There are two possibilities:
Something Corrupted
This is a long shot, but you never know when bits get tangled up somewhere and cause the weirdest things. As Nigel pointed out, start with the Preferences file.
Another step is to log in to a different user (if possible) and play around to see if you get the same behavior. If not, then it would point to a user file on your user directory, possibly corrupted. You wouldn't still know which one, but at least you narrowed it down and can keep on looking (and hopefully eliminating)
Pilot Error
As Nigel pointed out, there could be a combination how you do the editing which we don't see at the moment. Couple of things that come to mind
Aliases: This is only thing I can think of that "remotely" delete other Events, but you don't mention that you use Aliases (or do you?)
Are you doing the edits in the Piano Roll? If you have "Selected Region" selected in the Local View Menu (instead of the "One Track" option), then the following would be technically possible. Selecting Events in a Region and then going to a different Region keeps those Events selected. If you would go to the Piano Roll and and delete the visible Events, then technically some other Events form other (selected) Regions that are "out of side" but still selected could be deleted too. This is a little bit far fetched but technically possible.
Can you "Track Protect" the MIDI Tracks and only unprotect them when you are editing? This prohibits deleting of Events in those Region manually, and hopefully also those automatic deletion. I know this would be only a "band aid" solution, but if it works to avoid having notes deleted, it gives you time to search for the real culprit.
Hope that helps

How to control external MIDI multi-timbre device

I have an external midi device that has distinct buttons with which I can control on/off individual sounds. The device has a single midi channel but many different sounds that can be turned on/off in any combination - i.e., I can have two or more sounds turned on which the device mixes down to its stereo outputs.
Each specific sound has a name and can also be controlled with a midi message in the form of "Bn 49 xx" (on event) or "Bn 4A xx" (off event). I would like to be able to control these sounds from logic pro.
Note that I have refrained from calling these "sounds", "patches". A fundamental difference between a patch and a "sound" as I described above is that you can only select a single patch at the time - I need to be able to turn on/off any combination of these sounds.
Hope it is clear to someone what I am trying to do... your comments are most welcome.

After some serious support from Pancenter (thanks again!), I arrived at a working configuration using Apple’s Environment editor. In the hope that my learning experience is of use to someone else, hereby a quick write up.
My objective was to control the stops (programs) of two pipe organ modules from Logic Pro 9, preferably with a nice graphic interface. The modules are broken up into 3 sections that each have a direct midi channel. I already set them up on my midi controller and could play a midi file on them just fine but not the stops. Rather than a typical synth program switch, stops on an organ can be turned on/off in any combination thereby mixing the sounds together. The documentation I had showed these midi byte sequences for turning on/off a stop:
Bn 49 rr = stop on
Bn 4A rr = stop off
with ‘n’ being the midi channel, and ‘rr’ the hex code for a particular stop. With Pancenter’s help, I started playing around with a Fader/Button 3 on the “Click and Ports” layer from the Environment (command 8). A button can be used to send a variety of midi message types, in my case I need a Control message with its channel set to the appropriate midi channel of the pipe organ module (channel 2 for me). A midi control message has the form <control byte> <byte 1> <byte 2>. The byte 1 field holds the specific control and byte 2 the value for that control.
Buttons send their max value when on (depressed) and min value when off. i.e., the value of byte 2. As you can see from the midi sequences listed above, this creates a bit of a complication in my case because the value ought to stay the same but the control (byte 1) must change.
I decided to set the button values to the midi stop I wanted to control as the min value and the max value as the stop +1. So my button out going sequences are now:
Bn 74 34    stop off
Bn 74 35    stop on   this should be changed to Bn 73 34
(Notice that 74 = 4A hex and 34 = 22 hex)
Using a transformer object right after the button, I detect the Bn 74 35 sequenc and change it to the desired Bn 73 34. As it turns out... easy as pie when you get a little help from a friend ;-)
This is the button with output to the transformer:
The inspector details for the button:
The transformer setup:
The entire pipe organ module with stops, just need to clean up the names a bit and we're done. Notice that I used a fader text object for the stop headers.
I am a 2-3 week user of Logic Pro and must admit that I am starting to be thoroughly impressed with its capabilities. The Environment editor is ahhwwsome though perhaps a bit daunting at first.   Thanks again Pancenter for your totally cool help !

Problem with external MIDI routing has to be MainStage 2 bug

I posted a bug the other day where I was getting occasional bogus MIDI note events in one external synth while playing a keyboard that was (supposed to be only) sending MIDI data to a different external synth.
I have now performed two experiments that would seem to indicate that the problem must be caused by MainStage 2 and not by CoreMIDI or by MOTU drivers/external MIDI interfaces.
Experiment 1:
I created a new Digital Performer sequence, enabled multi-input mode and routed one keyboard controller to one external synth and another keyboard controller to another external synth, essentially reproducing the MainStage 2 patch. Played both keyboards together for some time with no problems whatsoever. (In MainStage 2, I'd get a glitch pretty quickly)
Experiment 2: (to eliminate the possibility that Digital Performer (a MOTU product itself) wasn't doing something special)
I used Max/MSP and created two midiin/midiout connections, one representing the first keyboard controller and external synth, the second representing the second keyboard controller and external synth respectively (duh). Again, I played both keyboards for a while and everything worked perfectly, no glitches.
I have reported this to Apple several times via their feedback but have heard NOTHING back from them.
Original bug posting
(http://discussions.apple.com/thread.jspa?threadID=2137282&tstart=0)

If I understand you correctly, I think I experienced a similar problem. However, in my case, I don't have two separate midi input devices, but rather one; and two separate external devices I am wanting to control with midi.
Brief background: I use an EWI to play various softsynths & now external synths via MS2. I also route the audio from my EWI into MS2 for additional processing and I use an external effects processor (Eventide Eclipse) for additional processing and sound manipulation. I send program changes with my EWI to change patches using MS2. My EWI transmits only on midi channel 1, which MS2 is set to receive on. Also, my Eclipse is set to receive midi data on channel 5 (a method I used to keep things separate in my all hardware rig when MOTU MTP AV was my switching device).
Initially, I thought I could just have my EWI send a program change message on channel 1, and then MS2 would send a program change message to the Eclipse on channel 5, all from the same MS2 keyboard object. It worked, but with one small glitch ... after the program change happened, and I started playing my EWI, the Eclipse began receiving my midi note information which in turn caused the Eclipse to be confused and start trying to change patches, etc. I checked the keyboard object which was not supposed to transmit on channel 1 to anything external, but I could not figure out how to set it up. Note: none of my devices are set to OMNI because I learned a long time ago, that I want to control routing and specific channels ensure their separation ... or supposed to anyway.
What I ended up doing was to create another midi object (this time the little spherical thing, not the keyboard), and assigned it to transmit on midi channel 5 and not receive on any channel. This turned out to be the solution / work around for this situation.
Another problem I am having with midi control when using MS2 as a go-between, is an issue with pitch bend information getting messed up as its sent to my external synth (Yamaha VL70m). For some reason, playing the VL70m by way of MS2, causes my EWI pitch-bend data to force the VL70m pitch-bend in the permanent down position making all notes flat. My solution in this case was to set up a direct link with MidiPipe, from my EWI to my VL70m and filter out any program changes so that I can use the MS2 to send a patch change to it, but use my EWI to play it directly. It seems to work well, and my pitch-bend is back to normal, but I am not certain (and don't know how to test) if the VL70m is now getting duplicate note on/off information with the potential of a minuscule delay from MS2 being in the path as opposed to playing direct from my EWI. It seems unnoticeable to my ears, but it's in the back of my mind.
Anyway, these are some of my midi episodes and I think it's pretty clear that Apple needs to quickly address some issues about midi handling and MS2.
Hope this helps ... and maybe we can come up with some more creative ways to deal with these "undocumented features" (to borrow a saying from the Windows world).

Phantom Noise During MIDI Events

Hiya,
I've searched a bit, but haven't found much. I apologize if this has been covered. (Obligatory disclaimer complete!)
Starting earlier this week, I noticed a noise would accompany any MIDI notes I'd play on my keyboard through Logic. Frustrating. I'm having some difficulty describing the noise, but I'll try. First, it has a distinct tone, which is the same tone as the note being keyed. Beyond that it's faint, full of static and has a bit of a phasing effect.
My troubleshooting so far: (restarting, shutting off and on, unplugging and plugging included!)
1) Removed my usb keyboard from the computer, and played MIDI notes through the caps lock keyboard. Issue persists.
2) Used the pencil tool to create MIDI events. Issue persists on playback.
3) Deleted the Logic plist. Issue persists.
4) Tested similarly in GarageBand. Issue persists.
It should be mentioned that I'm not having any other audio issues.
I'm currently reinstalling Logic, but I can't imagine that's going to change much considering the issue is cross application. (I will test older projects sequenced in the Before Time to see if those events phase as well as soon as Logic is done reinstalling.) I'm sure it's a simple solution that I am not familiar with. No doubt I'll kick myself when someone figures it out!
Thanks in advance!

It sounds like you might just be hearing electronic interference noise due to the fact that you're using the internal sound of the Mac. In the old days (up to around the time of the G5s), the built in sound on Macs was fairly decent quality, at least in terms of the way it was isolated to reject interference from the electronics running inside the box. More recent models don't seem to be quite as good in this regard,
This is what I thought when first reading this post last night. I have an old Fender guitar amp from the 50's that has the same sound. The same note, played low in the background with a quieter layer of distortion. (static).
It will show up most on tones that are closer to a pure sine wave, like some of the Rhodes/El.Piano sounds. You might not notice it on more complex tones. Also will show up more playing quietly.
What do you have set as the Mac's input device, is it set to Line input, if so try unplugging anything going into the input, just to see if there's some interference.
Also, what are you monitoring the sound through?

Assign an audio i/o or external midi ?

Ok, totally new to Logic (from a Pro Tools and Sonar backgrounds).
Just created a test project, have some external midi, some audio tracks, even a ''drummer'' track, but I just can't find a way (that should be basic...) to assign output (and eventually input) to an audio track, nor find the external modules (then channels) I have.
In Audio and Midi e=setup, I see both the RME Fireface 800 (audio) interface as well as the MIDI interface and attached keybords and modules. But no way I can see this in Logic.
What am I missing ?

Just thinking out loud - you could load it as a sample into Ultrabeat and play it that way? Osc 2 lets you load a sample and tweak it (very cool to play with too).
Give it a go.
Regards,
Shaun

Serious external Midi issues

Back in Logic 8, and earlier versions of Logic 9, I used to be able to just open up an external midi track, and play my keyboard out of it, but these days, the only way to hear an external midi is if I arm an audio track.... what's going on, what happened? and how can I make my keyboard sounds play just from the external midi... thanks!

Pancenter,
Yes.. I do see the occasional minor variations much like yourself when I sync up to my Oasys or more usually the Motif... to a fair sized and complicated project,,. Maybe +/- 1.. or on rare occasions +/- 2 bpm... but nothing close to the OP's +/- 5 bpm experiences...
It actually got better for me when I installed 10.8.x... along with the newest Motu drivers.. and in fact I can't remember the last time I had any unworkable issues with syncing though admittedly I haven't done that much syncing recently.
I do have a project coming up in the next 10 days.. that will require me to use the Oasys synced to Logic so I'll make a note of any issues i have and post back if any occur.
As an aside, I have recently been doing a lot of work with iPad Instruments and Arp Apps and Logic... and the sync as been rock solid over USB...

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
Don't be put off by the complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. As I wrote above, it changes nothing. It doesn't send or receive any data on the network. All it does is to generate a human-readable report on the state of the computer. That report goes nowhere unless you choose to share it. If you prefer, you can act on it yourself without disclosing the contents to me or anyone else.
You should be wondering whether you can believe me, and whether it's safe to run a program at the behest of a stranger. In general, no, it's not safe and I don't encourage it.
In this case, however, there are a couple of ways for you to decide whether the program is safe without having to trust me. First, you can read it. Unlike an application that you download and click to run, it's transparent, so anyone with the necessary skill can verify what it does.
You may not be able to understand the script yourself. But variations of the script have been posted on this website thousands of times over a period of years. The site is hosted by Apple, which does not allow it to be used to distribute harmful software. Any one of the millions of registered users could have read the script and raised the alarm if it was harmful. Then I would not be here now and you would not be reading this message.
Nevertheless, if you can't satisfy yourself that these instructions are safe, don't follow them. Ask for other options.
4. Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
5. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
6. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
7. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.

Copy the selected text to the Clipboard by pressing the key combination command-C.
8. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
9. If you see an error message in the Terminal window such as "Syntax error" or "Event not found," enter
exec bash
and press return. Then paste the script again.
10. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
11. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report what happened. No harm will be done.
12. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with the words "Start time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
13. When you post the results, you might see an error message on the web page: "You have included content in your post that is not permitted," or "You are not authorized to post." That's a bug in the forum software. Please post the test results on Pastebin, then post a link here to the page you created.
14. This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.
