HD on slower-than-2.0GHZ Mac

Apple says you need a 2.0 GHZ Core Duo Mac to play HD video. I have 2 Macs, one that has a 2.2GHZ Core Duo (a MacBook) and one that is "only" 1.66GHZ Core Duo (an older Mini). I have been playing HD TV shows and movies purchased from the iTunes store on the Mini, which is hooked up to a large-screen LCD TV) and don't seem to be having any problems. According to Activity Monitor, I am only using about 60% or 70% of the processor's capacity.
Am I missing anything here? Is there some problem I might have? Why does Apple say you need 2.0GHZ--just being cautious?

If it works then do it. There's only a few ways I can think of damaging a computer by simply running above spec. software. If a computer has to work so hard it overheats (more a sign of bad cooling than overworking). If a computer is having to revert to using the hard drive for memory, putting more wear and tear on the drive.
As the other poster observed, the 2GHz bar is set to play it safe. Maybe if you were running lots of other programs at the same time as playing movies you might notice decreased performance.

LR2 64-bit slower than 32-bit (Mac)

I ran a test a while back with Lightroom 1.3.1, generating 1:1 previews on a test directory of images:
http://www.rassoc.com/gregr/weblog/2008/02/24/mac-pro-performance/
On a Mac pro 2.8 GHz 8-core machine with 12GB of RAM, I found I could generate 211 1:1 previews for my directory in about 5:36, or 1.59 seconds/image.
I've found Lightroom 2, in 32-bit mode on the same machine, to run roughly the same speed.
However - running Lightroom 2 in 64-bit mode on this same machine takes 7:23, or 2.10 seconds per image. It's typically using >500% of CPU.
Why is it so much slower running 64-bit?

My results are repeatable; 1:1 preview generation takes about 30% longer using 64-bit than 32-bit. I opened a support ticket on this (case number 180331555) - here is the response from Adobe:
I understand that Lightroom# takes longer to render previews in 64-bit
mode than in 32-bit mode.
I am able to duplicate this basic behavior when rendering a relatively
small batch of previews in Lightroom.
It is not expected that all operations in 64-bit mode will perform
faster. Memory access generally takes longer in 64-bit mode due to
having to address a larger memory space.
Performance benefit should be most noticeable when performing operations
that use more than 4GB of memory. At this point, the 32-bit application
will experience a large performance penalty due to increased hard drive
access.
Hmm. Sounds like they were able to reproduce the behavior I see, but I can't think of why memory access should be slower in 64-bit.

After updating to Mavericks, my mac seems slower than ever.

Here is a report for my mac that maybe someone can help me figure out why. Is something not compatible?

I think i have a DVD of OS Lion which comes when i bougnt Mac laptop in 2011. Should i install OS Lion? What wil happen if i install OS Lion, do i lost my Applications or ...????

Hi, the last install dvd that came out for mac's was Snow Leopard,10.6.3. Lion is a download from apple. You cannot just install it over Yosemite. You would have to backup your drive to save files you want and do a clean install. You might want to look into getting more memory. You can run 8 Gig"s of memory on your Macbook Pro.If your Macbook Pro is getting really slow you might want to download EtreCheck and then post the results here.http://www.etresoft.com/etrecheck Check out this article. http://support.apple.com/kb/PH19031

Mac OS internet 5x slower than Windows 7 on BootCamp

Alright, here is my problem...
My one and only computer is a mid 2010 iMac... I recently moved to a new place. Prior to me moving I was stuck with an awful 3Mbps download speed. (You can tell how much I hated it by looking at my username) Now that I moved, I am able to get much faster internet. So, I got a plan that offers up to 50Mbps download speeds (Xfinity Blast cable internet). I didn't want to rent my ISP's modem/router, so I purchased my own. I got a Motorola sbg6580. As soon as I got everything hooked up, it seemed perfect. I used speedtest.net to see what I was getting. I first tested on Windows 7. To my surprise, I was getting around 70Mbps. I then restarted my iMac into the Mac OS to do some speed tests. On the Mac OS, I was getting around 50-60Mbps. A bit slower than Windows 7, but still very good. The next day I decided to do a "real world" test. I downloaded a 1 Gigabyte file just to see how fast it was. Now, if I was getting 50Mbps the file should have taken just under 3 minutes to download. Instead, it took around 7 minutes. I figured it was maybe just the website I was downloading from. (the file I was downloading was the Cry Enginge SDK - http://www.crydev.net/ ) I did some research and discovered the website testmy.net - I am not sure if this is completely reliable or not, but every test I do on testmy.net I get around 10Mbps. At first I thought it was my ISP ripping me off, then I decided to do a testmy.net test on Windows 7 via BootCamp. (please note that on both Mac OSX and Windows 7 I did multiple tests over the coarse of multiple days) On Windows, I could instantly tell that the test was going much faster. The results for testmy.net on Windows 7 were 50-60Mbps. I did not completely trust the website, so I downloaded the same Cryengine SDK on Windows. It took around 3 minutes, just as it should have. I researched a bunch online trying to find info on this problem. I tried many "solutions" but none of them changed anything. (these include but are not limited to: Tried different DNS servers, Disabled ipv6, disabled sbg6580 firewall, disabled mac osx firewall, tried changing the wireless channel, and reset sbg6580. I came to the conclusion that it was the sbg6580. I thought that maybe an airport express would give me better results. So, today I bought an Airport express. With the sbg6580, I was able to disable the router features so it was just a modem. I was then able to set up the Airport express as my router. It fixed nothing. I am still getting the same results, Windows is still getting anywhere from 50-60Mbps while Mac OSX is getting around 10Mbps. I am out of ideas, if anyone could please help me that would be great. Also, if you need to know anything else please let me know. I may have missed something...
A quick note:
At my old house I had my iMac hooked up to a surge protector. For maximum internet performance, my iMac was connected to my router with an ethernet cable. During a bad storm one day, a lightning bolt either hit my house or very close to it. Ever since, my ethernet port has not worked. I have tried multiple eithernet cables as well as multiple routers and networks. I do not have the money for apple to completely replace my logic board. - So anyway, I am unable to test the performace with an eithernet cable.
Extra information:
My sbg6580 as well as my Airport extreme are both sitting on the same desk as my iMac, so it is obviously not a signal problem.
I also own both a iPod touch 5th gen and a iPad 2nd gen. I am getting around 20-30Mbps on both of them. I am not sure what would be a "good speed" on either of these, but I figured that was pretty good for a tablet and ipod.
The upload speeds on both windows 7 and Mac OSX are around the same 5-10Mbps.
I am using Google Chrome on both Windows 7 and Mac OSX but, I have also tried Firefox and Safari.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, or by a peripheral device.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

I have found that my Mac Book Pro 15 inch late 2011 is slower than my PC Windows 7 for certain downloads, and working with iPhoto. Would adding RAM be helpful in speeding up this process. Currently I have the stock 4GB RAM, and storage 500GB HD drive.

I have found that my Mac Book Pro late 2011 15 inch is slower than I expected with certain downloads, or working with iPhoto than expected compared to my previous Windows 7 PC. Would adding RAM be of any value in speeding up the process?

PS CS3 much slower than CS2 on Intel Mac. I don't get it.

Yes, very very strange.
I work with very large files, so I just got a spiffy new Mac Pro. It's my first Intel machine, so I expected that CS2 would drag a little bit, due to Rosetta. In fact, moving from one processor to eight of them seems to have much more than compensated. Nevertheless, I ordered CS4 and while I wait I downloaded the demo of CS3.
I expected that CS3 would fly (no Rosetta) but have found my test tasks taking an inordinate amount of time... much slower than CS2 on the same Xeon workstation, and slower than CS2 on my old iMac (single 2.1GHz G5)
Since I work with extremely large files, I got a hardware RAID5 made up of four 15,000RPM SAS drives. I can't get enough RAM to avoid using scratch disk, so I attacked the biggest performance bottleneck. I did get 8GB of RAM; would have gotten more, but I read that it won't matter until CS goes 64-bit in CS5 at the earliest.
The rest of it: dual quad-core 2.8GHz "Woodcrest" Xeon processors, NVIDIA GeForce 8800GT graphics card, OS X 10.5.5, all updates (Apple and Adobe) applied as of 6pm Wednesday October 8th.
I'm running two tests as my benchmark: open a file (PSD created with CS2, 75" x 75" at 400ppi, two layers, RGB with one additional channel) and resize to 75" x 75" at 800ppi. Once that is done, I rotate the new, massive file counterclockwise 18.5 degrees.
On my old setup, 2.1GHz SP G5 iMac with CS2, these tasks took 38m 30s and 1h 33m 22s respectively.
New machine with CS2: 10m 09s and 29m 14s respectively
New machine with CS3: 42m 38s and 1h 36m 24s
(above tests run repeatedly: these numbers are the fastest numbers for each configuration)
I have nothing else running for these tests, except for Activity Monitor. What I've observed with Activity Monitor: the old G5 was pegged at (or very near) 100% CPU the whole time. Mac Pro with CS2, Photoshop ran most of the time on one CPU at a time, but spiked up as high as 250% CPU usage just for Photoshop.
I haven't seen Photoshop CS3 use more than 80% of one processor the whole time on the Mac Pro. Mostly it sits around 35%.
One more informal test: if I open that same file and downsample from 400ppi to 200ppi, CS2 does it in 1m 40s. CS3: 6m 57s. I don't have the iMac any more so I can't tell you how long it would take there.
In both CS2 and CS3 the scratch disk is my startup volume, but it's a RAID. I can't add any more drives except for external drives. I could have configured it to one dedicated system drive and a second scratch volume made up of the remaining three drives, but I consulted with people who know RAID better than I do who agreed that since everything is going through the SCSI controller and everything gets written to multiple drives in order to make it faster that I'd get a performance hit by splitting the RAID into two volumes, even if multiple processes are trying to get at the same drive array. Even adding a Firewire 800 drive for scratch would be slower than using the RAID. Or so I've been told.
So, this seems absurd. CS3 is not using Rosetta, right? So it should be flying on my machine. What on earth could I have done to a fresh CS3 (demo) install to make it slower than CS2 on my old G5? Is the CS3 demo crippled? Is there a conflict having CS2 and the CS3 demo on the same machine?
I'm stumped.

>Ya see, this is the attitude you really, really should get over. The Photoshop CS3 (10.0.1) code is just fine... it's your system (hardware/software) which, for some reason is not providing an optimal environment.
Jeff, I agree completely. You seem to be assuming that I actually think Adobe wrote bad code. In fact, I believe Adobe did NOT write bad code (and I wrote that) but that the condition that you are suggesting (CS3 being slowed by having having scratch and system on the same volume to a far greater extent than CS2) could only be caused by bad code by Adobe. Since I believe that, as you say, a universal difference of this magnitude between CS2 and CS3 would be noticed by huge numbers of users, I doubt that what I am seeing is the result of having scratch and system on the same volume.
In case I'm being less than clear:
Scratch and system were on the same volume for CS2.
Scratch and system were on the same volume for CS3.
On my system CS2 performs tasks three to four times faster than CS3.
ergo, either there is some problem other than scratch and system being on the same volume (perhaps something that exacerbates the scratch/system/same volume issue, OK, I accept that possibility) or else the change has been between CS2s and CS3s handling of scratch disks.
If for the sake of argument we rule out the possibility that CS3 handles the condition of scratch and system being on the same volume worse than CS2 does, the only possibility left is that there is SOMETHING ELSE WRONG WITH MY SYSTEM.
I am trying to find out what that other thing is. You're the one insisting that scratch and system being on the same volume is the cause of the CS3 slowdown. Accusing me of not believing that there's something wrong with my system misses the mark entirely. I ABSOLUTELY believe there is something wrong with my system.
> Your RAM tests sound pretty thorough, but if I had your large-files workflow I would buy two (or preferably 4) 4-GB sized matched RAM DIMMs, remove all the existing RAM, and install only the new RAM to further test whether or not the old RAM is anomalous.
Thanks Allen,
Actually, this is exactly what I've done, though in a different order. My system shipped with two 1GB chips. I bought two 4GB chips from OWC and installed them, and found my CS2 performance to increase significantly. It was only then that I tried installing the CS3 demo. When I found CS3 running my tests more slowly than expected, I pulled the new RAM out and tried with just the original 2GB and tested both CS2 and CS3 again. Then I took the original 2GB out, put only the new RAM in and tested CS2 and CS3 again, finding the same results. Currently I have all 10GB in the system and for the moment I'm setting aside the possibility of a problem with the RAM (or at least setting aside the possibility that the RAM chips are just plain bad) because that would indicate that both the new and the old RAM are both bad in the same way. That seems unlikely.
So I guess I'll have to drag the system down to the Genius Bar if I don't see an improvement from rearranging my hard drives.
The update there is that last night I backed up my system, and this morning I deleted my RAID5 set, blowing away everything on my system until I can restore from backup. The new configuration is 1 JBOD drive plus three drives attached as RAID0.
Unfortunately, neither of the new volumes is visible when I go to restore from backup. For the moment, this little experiment has cost me my entire system. The upshot is that it may be some more time before I have any more information to share. Even when I do get it working again, I can expect restoring to take the same 12 hours that backing up did.
I will certainly post here when I've got my system back.

On Mac FAT32 Format Slower Than HFS

My 60GB iPod came in Windows FAT32 format which I liked since I could use it in disk mode on both Mac & Windows. However it seemed slow to start playing video and when switching between video files.
I did some timing tests and on the Mac FAT32 was much slower than HFS.
FAT32
Start playing movie = 12s
Stop movie and restart at same location = between 12-30s
HFS
Start playing movie = 5s
Stop movie and restart at same location = between 6s
If you have a Mac and your new 5G iPod is formatted for Windows, you may want to use the iPod Updated to restore and make the drive HFS.

> conversion being done internally? Any workarounds?
Well, there isn't any endian conversions going on. Both the file and
Mac memory model are big-endian. But the classic Mac file I/O is pretty
slow. The only thing I can recommend is to do the reads in larger
blocks. I've also heard some people claim that running their file I/O
bound apps underneath OSX will speed things up. In other words, running
an OS9 app underneath OSX is actually more efficient because it replaces
all of the OS9 code. So, you could give that a shot.

Why does my Mac hang at some point? The startup is slower than usual and sometime's the graphic glitches occur. please help!

My mountain lion OS hangs like windows does and sumtimes have visual glitches like the drop down menu's are half visible. Sometimes it slows down at every point. And its just 2 months old. Please help.

Isolating Issues
Do a backup, using either Time Machine or a cloning program, to ensure files/data can be recovered. Two backups are better than one.
Try a restart.
Run Disk Utility/Repair Permissions. Run until it reports no errors. If there is a recurring error, see the article on what permission errors can be ignored.
Disk Utility
Disk Utility Repair Permissions You Can Safely Ignore
Try setting up another admin user account to see if the same problem continues. If Back-to-My Mac is selected in System Preferences, the Guest account will not work. The intent is to see if it is specific to one account or a system wide problem. This account can be deleted later.
Isolating an issue by using another user account
If the problem is still there, try booting into the Safe Mode. Shut down the computer and then power it back up. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart. For each disable/delete, you will need to restart if you don't do them all at once.

New Mac Mini slower than my 4 years old iMac

My Intel iMac (20" display) four years old is out of order (I think the Power Supply was gone), and I bought the new entry level Mac Mini.
When I started using it I noticed that it's much slower in several tasks than my old iMac (when restarting, when opening applications, when working with an app with another appl in the background, etc. etc.). I was concerned about this, but then I asked some friends that have Mac minis and they said that it's normal.
Why? Why a computer with a new i5 Intel processor can be slower than a four years old iMac Core 2 Duo? Is it because of the slow drive (5200 rpm)? Or what is the explanation? If this is normal for the mini, I'll try to fix my old iMac as soon as possible.

Don't downgrade to Lion. For what it's worth, my experience with Lion and Mountain Lion has been almost the exact opposite than what CaptH reported: I find ML to be much faster and more reliable, both on my late-2012 Mini and my mid-2007 iMac.
Your perceived speed issues are almost certainly a result of the slower-spinning hard drive in the Mini as Shootist007 pointed out earlier. Go ahead and disable Spotlight if you want to, but once the indexing is complete (which can take a few hours – or even a few days if you have a lot of data) it shouldn't be a problem unless you are continually connecting different large external drives.
Get the latest Combo Updater and install that. If you have some minor OS issue, that should solve it. Do a normal Software Update / check the Mac App Store for updates after you install the Combo Updater. Get it here:

If you continue to be bugged by the slower speed, see if your local Apple Store will allow you to exchange it and a little extra money for an equivalent model with a Fusion Drive. Or go to Other World Computing and purchase their kit to add a second drive, and use it to add an SSD in the second drive bay:

Also, RAM is super-duper-uber-cheap right now. If your Mini has only the stock 4gb of RAM, you might be pleasantly surprised by the improved performance by doubling that. I have 16gb in my Mini, it cost me well less than a hundred bucks, and it makes everything better including graphics performance. But if you don't do something to work around that slow 5400rpm hard drive, it will always be the bottleneck in your system.

Stabilization Slower Than Ever. :( New 12 Core Mac Pro VS 2006 PowerPC Dual

I have concluded testing that the WarpStabilizer in AE using a 12 Core 2.9 GHZ Mac Pro is SLOWER than a dual 2.7 GHZ PowerPc G5 running iMovie and GeeThree's Stabilizer plugin.
There is no excuse for such shotty performance.

Rick:
Stabilization needs to occur in edited clips. If you don't the stabization data is excessive for centering the frame. The edit comes from within PP. Once a PP project is ready for the Dynamic Link(s) .. a 30 min clip could have 100s of clips that need to be sent to AE via DL.
To do this with one giant 30 min. clip sends the position tracking data all over the place .. and ruins many frames that would otherwise be fine if the clips where divided appropriatley ..
Try it .. or anyone whom wrote the plug in should try it.
It is a very simple process that I expected to do within a very basic function.
The was PP and AE handles it is ______.
I would love to make a demo video about what is happening. :O

Why is Mac OS X 10.7 so much slower than Snow Leopard? It isnt smooth, applications are slow and most dont respond, and dowloads take hours, minutes.

Something is seriously wrong with your installation or you are critically low on RAM, like below 2 GB.
How much RAM is in your machine?
Have you tried a Recovery?

My MacBook Air shut down is slower than other macs I have seen

I think this is due to the recent Mac OS 10.8.2 update
My MacBook Air shuts down slower than usual. It will get slow and show a white screen with a spinining wheel taking up to 15 seconds.
This is longer than the startup time.
When it was new, I think it was running Mac OS 10.8.1. Shutdown was super speedy and took maybe just 3 seconds. It then asked me to update, so I obviously did, since I thought new improvments were made.
So how can I get rid of this slow shut down timings?

You might try resetting the SMC. If that does not work, take it in for service (you are under warranty).

After Effects Render SLOW - Slower than my old PC

I am using a new 1 month old 20" iMac, 2.0Ghz with 4gb DDR2 RAM, running OS X Leopard. Adobe After Effects CS3 is rendering really slow, and I mean like the same as my PC. Also the same with Premiere Pro, it renders really slow and I have tried different formats too, in premiere pro it took 2 hours to render a 5 minute video (saved to .mp4 640x480 pixels, end size was 20mb). This is wayyy to slow.
I compared my Mac with my old PC running Windows XP, it is pentium 4, 3.2Ghz with Hyper threading technonlogy and 1.5 GB DDR Ram. I tested rendering andrew kramers 3d room tutorial, I downloaded the project file. I only chose to render some of it and the old PC was FASTER than the Mac by around 15-20%. BUT, the mac was ONLY using 6% of the 3gb (it only recognises 3 gig not 4 but I dont mind that too much) and the PC was using 60-70% of the 1.5GB (thats using more RAM than the mac) So why can't I get the Mac to use more RAM when rendering, and why is it slower??? It is faster at EVERYTHING else, well the ram preview is about the same.
How can I get my mac to use more of the RAM and why is it rendering and previewing the same if not SLOWER than my 5 year old PC?
Any help would be awesome, thanks

RAM allocation is dynamic, you cannot enforce anything on that end. AE takes what it needs and no more. I would think that your issue has to do with the graphics card/ chipset, so my first suggestion would be to make sure you have updated your AE to the 8.0.2 patch. Secondly, run a software update for your Mac. If neither of this applies and brings any betterment, disable the AE_OpenGL.plugin. Simply delete it or move it outside the AE directory. Most certainly your issues hinge on your graphics hardware, so one of the previous recommendations should yield a noticable effect.
