Macbook Pro Won't BootUp/Recognize ANYTHING!

Hello guys,
I was using the TechTool that came with my Apple Care. I noticed that my system was running slowly, even though I wanted to do other things because of it. My system then froze, so I force-shutdown the computer. When I go to restart (and press the option key), I don't see ANYTHING. Even when I try to boot up from the Apple Boot Disk (that came with my MBP), it doesn't recognize it in that screen. All it shows me is a mouse icon which I can move. (Doesn't recognize any USB devices, either). Pressing the "C" key on startup did not work while the disk was inside..
Any clues?
Thanks,
Noam.
EDIT: When I start it up, I hear the chime, and obviously see the white-ish screen. However, I don't see any Apple Logo.

When troubleshooting (if you have not already done so) disconnect all devices from your computer.
"I was using the TechTool that came with my Apple Care. I noticed that my system was running slowly, even though I wanted to do other things because of it. My system then froze,"
Probably because you are using an outdated version of TechTool Deluxe. See Article http://support.apple.com/kb/TA26636 AppleCare Protection Plan CD: How to Update TechTool Deluxe
"it shows me the folder with the flashing question mark. What should I do????"
Try the suggestions mentioned in Article: http://docs.info.apple.com/article.html?artnum=31355 Mac OS: Flashing Globe When Computer Turns On or *A folder that has an alternating flashing question mark*
You can also try running +repair disk+ from your *software install DVD* and afterwards, run +repair permissions+ *from your HD.*

Bluetooth in MacBook Pro won't pair with anything

Hello all. I have two MacBook Pros, each about 6 months old. They are both running the latest version of Lion. Neither one will pair with any bluetooth device. I always get an error message saying "this device does not have the necessary services". What does this mean, and how can I fix it?
I have a Canon printer that won't pair, and I thougth it was just a compatibility issue until I tried to pair a Jawbone Jambox (which used to pair), and a brand new Bose portable speaker. I get the same message every time.
Bluetooth on the computer finds the device, but can't go through with the pairing.
Any help would be greatly appreciated.
Thanks in advance,
Jadrb

I just got a Creative D100 bluetooth speaker and am having the exact same problem you had. Speaker pairs just fine with my ipad, but won't work with MacBook giving me same "This device does not have the necessary services" error message. Have you found a solution yet?

MacBook Pro won't boot to anything, help

This problem has to do with bootcamp:
My MacBook Pro isn't giving me either the System Recovery or OSX boot options on startup, I am only able to choose Windows, which now gives me a BSOD.
I installed windows this morning the correct way, with bootcamp assistant. Once in windows, I wanted a partition to share files between OSX and Windows (FAT), so when I tried to accomplish this, I:
-Shrank the windows partition (using disk management in Windows) to about 150gb less than I had originally partitioned it to be with the Bootcamp Assistant.
-Tried to make a new volume out of this unallocated space in OSX because I figured it was safer that way, but OSX showed that it was reading the unallocated space as STILL being a part of the bootcamp partition.
-I decided to create a new volume using Windows' Disk Manager, went through the steps, and it told me that the "New volume will be converted from a dynamic "volume" to a "basic" volume. I thought all was ok, didn't really think it mattered what the new volume was, but it converted all volumes to the green label (I'm guessing that's a basic disk)
-Now I get no option to boot to recovery HD or to OSX, only windows, which gives me a BSOD. (I can start disk repair, but it doesn't fix anything)
Reset PRAM, Reset SMC, tried windows recovery to at least get windows back from the dead.
I don't currently have access to my Lion install flash drive to try and repair my disk, but will by the end of next week. Obviously even if I still get windows working, I cant make a new one because you can only obtain Lion from the App Store. (Is there another way, or some disk repair utility I can install to a flash drive using Windows and then boot to?)
I guess my questions are:
-Will this accidental conversion of my MacBook volume from Dynamic to Basic effect my files there (Ie. did my stuff get wiped)
Drive letters and names were still there, leading me to believe nothing was formatted.
-Would converting the volumes back to dynamic fix everything?
Thanks guys

Did some research, what I did was acidentally convert my disks to dynamic, and dynamic doesnt allow you to boot from them, so if I were to plug this macbook's HDD into another computer and them use that computers disk manager to convert them back to basic, would they then be usable again, or have I caused damage that requires a reinstall.
Thanks

Macbook Pro won't bootup past grey spinning wheel, disk repair done

Hi,
Earlier today I tried to install something and found that for some reason whenever I clicked on the lock there was a slight flicker but no password box came up. I checked all my admin settings but again I was unable to do anything. So I restarted, and then my headache really began. The laptop would not boot up past the grey spinning wheel screen. I performed all the steps that are suggested elsewhere on here, tried resetting PRAM etc etc. I then managed to boot up in disk mode, opened disk utility and verified my hard drive, it said there were issues so I repaired. Thinking everything was all good to go I restarted but got the same issue again. Went to disk mode again and verified my HD just to make sure, again it said the disk was fine yet it still won't go past the grey spinning wheel screen! Please help...

Sounds like it's time for an Archive & Install of your OS. If you were able to boot at all, I'd suggest applying the OS X 10.6.4 Combo Update in hopes of overwriting whatever file(s) is/are damaged with new copies of them, but since you can't boot, that's not an option.

HT4650 My macbook pro won't bootup

Everytime I tried to start my my Macbook it shows me a block sign or a folder sign with question mark. This was after I shut down when Safari quit responding

Which specific version of 10.6 are you running? Are you able to boot your system at all, or does it stop at the point where it shows you the blinking folder with the question mark?
That blinking indicates it can't find a valid System to boot from, so there's a problem somewhere. These things don't commonly appear when you shut down after a program becomes unresponsive, so what else did you do that might have caused this, and exactly how did you shut down your Mac?

My MacBook pro won't recognize hard drive I put in it. It boots only to a white screen unless I boot to my recovery USB. If I do that then I can select my USB and my external time machine drive in the disk utility, so no problems there. But what do you

My MacBook pro won't recognize hard drive I put in it. It boots only to a white screen unless I boot to my recovery USB. If I do that then I can select my USB and my external time machine drive in the disk utility, so no problems there. But what do you think it is? It won't recognize any hard drive I put in the machine, so might it be the sata cable?

Boot the Recvoery USB, use Disk Utility to select the internal drive makers namea and size on the left.
Now select erase and select the midde option and click erase, it will take a bit to complete but it's best for the drive.
Now select Partiton tab, click the big box and Options: GUID and then Format: OS X Extended journaled and click apply.
Quit and you should be able to install OS X now with your Apple ID and password.

MacBook Pro won't recognize 1TB external drive

Hey team,
My mid-2010 MacBook Pro won't recognize my WD My Passport 1TB drive. I was copying files from the drive to my computer when my computer went to sleep (didn't run out of power, just went to standby mode). Turned computer back on and now it won't recognize the drive.
It is a USB 3.0 cord (computer is only USB 2.0 and the cord works with other drives) and when plugged in, the light turns on and the disk spins but isn't recognized my this or other computers (also not in Disk Utility).
Tried a handful of disk recovery programs but nothing wants to 'see' the disk plugged in.
Thanks for any and all suggestions.

yes yes yes, I warn people about WD drives on this link:
Your dead external hard drive is likely fine! Great hope for your 'faulty' external HD

What now?
Only option is to buy the SAME exact HD and swap controller boards, or pay someone a LOT more $$$ to do the same thing.
its not soldered there, its just a controller/ SATA "one piece"
They do that to save 50 cents in mfg. costs.
I mention your "issue" in that link. Which is why you do NOT buy WD ext. HD.
they make the controller board and SATA card one piece.
CURRENT MFG. THAT HAVE controller board and SATA cards as one piece are : WD USB drives, and Toshiba USB Canvio
However Toshiba didnt USED to do that, but they started doing it at the end of 2013.
avoid those 2.
To avoid that nonsense, buy Hitachi drives in USB.
Or, the best option:
Save money and invest in a bare hard drive backup and redundancy plan
Its cheaper
less fuss
more reiable, removes the nasty failure point of SATA card interfaces.
takes up lot less space.
Bare hard drives and docks. The most reliable and cheapest method of hard drive data storage, archives, and redundancies
The best method for your data archives and redundancies, which is also the least expensive, the most reliable, and the most compact option is the purchase of naked hard drives and at least one USB 3.0 HD dock ($40 roughly).
While regarding Time Machine and your Macbook or desktop, your primary backup is best saved to a conventional USB (or Firewire / thunderbolt) hard drive inside an enclosure, the most important part of your data protection begins after your 1st / primary Time Machine / backup; and these are your secondary (most important) data storage devices, archives and their redundancies.
However bare hard drives and docks (below) also work perfectly as a Time Machine backup, this is for home use, since the docking station is certainly not very portable as a notebook Time Machine backup device should be; nor should bare HD be packed around with a notebook, rather remain at home or office.
Six terabytes of 2.5" HD pictured below in a very compact space.
Bare hard drives and docks have the lowest cost, the highest reliability, and take up the smallest storage space
Drawbacks:
1. Care and knowledge in general handling of naked hard drives (how not to shock a bare HD, and how to hold them properly). Not a genuine drawback.
Advantages:
1. By far the least expensive method of mass HD storage on a personal basis. Highest quality naked HD can be purchased in bulk very cheap.
2. Eliminates the horrible failure point of SATA bridges and interfaces between external drives and the computer.
3. Per square foot you can store more terabytes of data this way than any other.
4. Fast, easy, no fuss and most simplex method of data storage on hard drives.

Need a printer for my old iBook (old apps won't translate) but also for a MacBook Pro, 10.6.8! Anything compatible?

Need a printer for my old iBook (old apps won't translate) but also for a MacBook Pro, 10.6.8! Anything compatible?

If I understand this correctly, you wish to print from the iBook under Mac OS 9.2.x and from the MacBook Pro under Mac OS X 10.6.8 (no AppleTalk support in the latter).
What type of printer did you have in mind? Does it have to be colour? Otherwise, a monochrome laser printer may be the best choice (high print quality and a low per page cost). A networkable PostScript printer may be the most compatible. Additional information would make it easier for someone here to suggest a solution.
If you would be willing to accept some extra work and certain limitations, another way could possibly be to "print" to a PDF file on the iBook via a printer driver called PrintToPDF, and then transfer this file to the MacBook Pro and carry out the "real" printing there.

My Macbook Pro won't type anything.

My Macbook Pro won't type anything. I have Mac OS X version 10.5.8. I can hold my off button to turn it off to reboot and put in my password on the grey screen but once I'm in, I can not type anything! PLEASE HELP!

So your keyboard is not working. Bring it to an Apple store or AASP.

My MacBook Pro won't let me mount my external Hard Drive. Just trying to restore my iTunes library.

My MacBook Pro, less than a year old, started acting weird. I backed everything up, took it in to Best Buy, who sent it out to Apple Repair and they put in a new motherboard.
It's running on Mac OS X Version 10.7.4
Now I am trying to put everything back on the computer from my external Maxtor 80GB Hard Drive. MacBook Pro won't recognize the external drive.
I tried Disk Utility. I can see the external drive, and did a repair disk and verify disk. Several times. Each time it says "This partition map seems to be ok."
However, I am not able to mount it, as that option is greyed out and i can't select it.
Also, under the Icon for the external hard drive, it has the Macintosh HD Icon (essentially my computer). I tried to restore this way, didn't work.
I need this to mount, as it has all of my itunes stuff on it; dozens of my sons movies, and my entire iTunes library.
PLEASE HEEEEELP!! HOW CAN I MOUNT THIS EXTERNAL HARD DRIVE? Thank you in advance

Try things in this USB/Firewire faq.

Hi! My MacBook Pro won't start! HELP !!!

Hi! My MacBook Pro won't start! I have tried everything I can think of like Safe Mode (doesn't work), Recovery (does not find Recovery Drive), Booting with OS Snow Leopard Cd (doesn't work)...
I have really no clue about what to do now... I paid quite a lot of money for this computer and am pretty short of money nowadays! Would like to repair with help rather than having to take it to Apple Store.
Has anyone had this same problem?
All I get is white screen + grey Apple and spinning grey disk... it's 100% frustrating! Any help would be more than welcome since I think i've tried EVERY SUGGESTION on this Support Center and Youtube videos...
This MBP is from 2011, runs on OS X 10.6.8
I tried booting with OS X Snow Leopard CD, it didn't work! (my cd player works! recognizes the Snow Leopard CD, but then never opens it... goes back forever to the with screen + apple and spinning disk)
I don't care about the content, it's OK if i lose all DATA... I just want to bring this Mac BACK TO LIFE!
When i run coomand on root# fsck -fy --> RESULT = my HD was checked and seems to be FINE!
Thanks

Please make a Genius Appointment and take it in for service.

My Macbook Pro won't boot up, only in safe mode!

Help, my macbook pro won't restart, only in safe mode! and it seems that safe mode has plenty of implications for use. my usb memory stick doesn't seem to be recognized while in safe mode. I was doing a cleanup on mackeeper just after I downloaded a trial version of microsoft office mac. The trial wouldn't work properly so I deleted it and decided to do a cleanup with mackeeper. than the mac froze while mackeeper was doing it's cleanup and the screen flashed black a few times. Ever since it won't boot up unless I use safe mode. Also, I downloaded the most recent updates while in safe mode but it doesn't seem to be recognizing that I already downloaded them because software update is still telling me that I have 6 updates. So I am horribly confused at this point. Please help, I need this laptop to do report cards (it's a good thing I got an extension). thanks

Please read this whole message before doing anything.
This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions — they’re easy to carry out and won’t change anything on your Mac.
These steps are to be taken while booted in safe mode.
Below are instructions to enter some UNIX shell commands. The commands are harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of the procedure suggested here, search this site for other discussions in which it’s been followed without any report of ill effects.
The commands may line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then either copy or drag it. The headings “Step 1” and so on are not part of the commands.
Launch the 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.
When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign.
Step 1
Triple-click the line of text below to select it. Copy the selected text to the Clipboard (command-C). Then click anywhere in the Terminal window and paste (command-V).
find /Sy*/L*/Ex* -type f -name Info.plist -exec sh -c '/usr/libexec/PlistBuddy -c "Print :CFBundleIdentifier" "$1" 2> /dev/null | egrep -qv "apple|Accusys|ArcMSR|ATTO|CalDigit|HighPoint|hp-fax|JMicron|print|SoftRAID|stex" && echo ${1%*.kext/*}.kext' {} {} \;
Post the lines of output (if any) that appear below what you just entered (the text, please, not a screenshot.) You can omit the final line ending in “$”.
Step 2
Repeat with this line:
ls -1A /e*/mach* {,/}L*/{Ad,Compon,Ex,Fram,In,Keyb,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Spo,Sta}* L*/Fonts 2> /dev/null
Important: If you formerly synchronized with a MobileMe account, your me.com email address may appear in the output of the above command. If so, anonymize it before posting.
Step 3
osascript -e 'tell application "System Events" to get name of every login item' 2> /dev/null
Remember, these steps are all copy-and-paste — no typing. Also remember to post the output.
You can then quit Terminal.

My MacBook Pro won't go beyond a white screen, after I pushed the restart button. How can I get it to a login? I have routinely backed it up, but don't know how to bring that up, nor if I have a boot file on that external disk. Help!

My MacBook Pro won't go beyond a white screen, after I pushed the restart button. How can I get it to a login? I have routinely backed it up, but don't know how to bring that up, nor if I have a boot file on that external disk. Help!

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
To restart an unresponsive computer, press and hold the power button for a few seconds until the power shuts off, then release, wait a few more seconds, and press it again briefly.
Step 1
The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
d. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If a desktop Mac hangs at a plain gray screen with a movable cursor, the keyboard may not be recognized. Press and hold the button on the side of an Apple wireless keyboard to make it discoverable. If need be, replace or recharge the batteries. If you're using a USB keyboard connected to a hub, connect it to a built-in port.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 11. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
Step 9
If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.
Step 10
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 11
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 12
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 13
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

Macbook pro won't boot, stuck on white apple screen

Noticed today, that my macbook pro won't boot . It gets to the white apple screen with the spinner under the apple logo. It stays like this for a long time without doing anything except spinning.
I've powered down and tried to boot up several times.
I have boot camp and windows on my mac and when the white screen appears, I can press Option to bring up which hard drive and the Windows partition will load without any problems.

Exacty what happens when you try to boot up from the disc that came with your computer? Are you holding down the c key? Have you tried holding down the "option key?" Are you able to run the Hardware Test - Intel-based Macs: Using Apple Hardware Test
Shut down your computer and disconnect all peripherals (keyboard & mouse if pertinent) from your computer. Now reboot.
If the Mac starts up normally, shut it down again and then plug in one of the peripherals (keyboard or mouse first) and start up your computer again. If it does so successfully repeat the process, adding one peripheral at a time until your Mac acts up. At that point, disconnect the last peripheral you added, reboot your Mac and search the peripheral vendor's website for an updated driver.
If no driver exists or the problem remain after installing the new driver, try a different cable or a different port on your Mac.
If none of the above works, again disconnect all peripherals from your Mac, hold down the "shift" key to start up in "Safe Boot" mode.
If the Mac starts up correctly, restart without pressing the "shift" key.
If your computer still does not start up properly, shut it down and restart it while holding down the Apple+Option-P-R keys; keep holding "all 4 keys" down until you hear the startup sound "twice."
If none of the above work Disconnect all peripherals from your computer. Boot from your install disc & run Repair Disk from the utility menu. To use the Install Mac OS X disc, insert the disc, and restart your computer while holding down the C key as it starts up.
Select your language.
Once on the desktop, select Utility in the menu bar.
Select Disk Utility.
Select the disk or volume in the list of disks and volumes, and then click First Aid.
Click Repair Disk.
(If Disk Utility cannot repair, you will need a stronger utility (3rd party) - Diskwarrior or Techtool PRO)
Restart your computer when done.
Repair permissions after you reach the desktop-http://docs.info.apple.com/article.html?artnum=25751 and restart your computer.
Remove any 3rd party ram.
Reinstall Lion - This will install a "fresh" copy of Lion without archiving old system files but leaves the rest of your files in place.
If your computer is still under warranty or you have Apple Care, take full advantage of it by letting tech support deal with your problems. It's what you're paying them for.
Out of warranty - take the computer to an Apple store or an AASP. Whichever is more convenient for you.

Macbook pro won't boot after installing update 10.9.3

macbook pro won't boot after installing update 10.9.3

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, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login 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, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.
