Introduction
I many a times see people asking questions about how to fix that or do that on OSX. This guide is to give a one stop shop for a majority of the common issues that I see out there for OSX.Tools
Techtools 5/6 (Techtools 5 for PPC) - Great for doing quick tests on hardware and surface scans. Also has some nice software tools built in.
Disk Warrior 4.4 - For repairing OSX and volumes - 4.4 is required for 10.8. 4.0 if booting from PPC
Winclone - needed if you have BootCamp. Can clone and resize Windows paritions
PPC Application Removal Script
OSX Install disk for your version of OSX
Applejack (for 10.6 and below) - For repairing disks and permissions. Requires booting into Single User mode.
Some terminology and info
Archive and Install - Boot from the OSX install disk, and perform an install. 10.5 and below require you to click the customize button to select Archive and install. 10.6 and above will do this automatically. 10.3 and below do not support Archive and install.
Permission repair - Disk Utility > Select OSX partition > Select permission repair
Verbose - Right as soon as you here the chime, press and hold the Command and V keys at the same time
Single User Mode
AASP - Authorized Apple Service Provider - I work for one and we can generally work outside the rules and restrictions Apple imposes the repair of its machines... mostly.
RAM (based on average user)
10.4 Tiger - Min. 256MB - Prefers 1GB
10.5 Leopard - Min 512MB, Prefers at least 1GB.
10.6 Snow Leopard (Sleopard)- Min. 1GB - Prefers 2GB
10.7 Lion - Min. 2GB - Prefers 4GB
10.8 Mountain Lion - Min. 2GB - Prefers 4GB
Common issues
OSX is running slow. I get a lot of beach balling
This is a common issue and has many causes. Things to check
- How much RAM do you have?
- Does it happen everywhere?
- If not, what application
- Possible Software issues in OS
To does:
- Check hard drive space - OSX requires at least 15GB free to work properly
- Surface scan - If passes check below
- Check ram
- Remove PPC Applications (if you don't need them). See below post.
- Repair permissions
- Repair disk
- Rebuild with Disk Warrior
- Archive and install
Last resorts:
- Save data restore - Clean install and just restore ONLY data. Reinstall all programs. DO NOT MIGRATE
- Possible hardware issues - Possible hard drive, hard drive cable. Maybe logic board. Bring to service center
Safari is crashing/running slow. Help?
Safari is annoying sometimes.
To do:
First Step
- Close Safari completely (force quit works best)
- Press Command + Shift + G - Type in ~/Library/Preferences - Look for com.apple.Safari.plist and remove it
- Restart Safari.[
Issues still? Lets continue.
- Go to ~/Library/Internet Plugins and /Library/Internet Plugins. Remove all plugs other than what is listed.
- Remove ALL internet plugs by moving them to a folder called Disabled. DO NOT move Quartz, Quicktime, Java, or nslQT plugins. You WILL break Safari completely.
- Restart Safari and reinstall Flash.
Still issues?
- Reset Safari - Go to the toolbar with Safari open. Go to Safari > Reset Safari. Select all and reset.
Still issues?
- If all else fails, delete Safari.app from Applications and restore a known good one from another machine running the same OS. Then repeat everything above.
My Mac won't boot. Sits at a white screen with a Apple spinny thing/blue screen/just plain white screen.
This one is always fun and usually means there is a hard drive failure. Somtimes it is just software, but usually not.
To do:
- Boot to Verbose. Look for anything strange. If you see anything about Disk I/O errors, hanging at a particular task, or anything about .kext, the drive may be shot. Run a surface scan. If you see even ONE bad block, stop the test and replace the drive. Follow my data recovery thread for additonal help. If not, take to a repair shop. Apple Store will NOT be able to help you. Ask for the best AASP in the area and go to them.
- If you don't see any issues and it is hanging, and surface scan passes. There may be a software issue but it may be a bad hard drive cable. Attempt a diskwarrior. If that doesn't work, attempt to repair the disk. If that fails, go to an AASP.
- If you don't care about what is on the mac, Reinstall the OS IF the disk is fine. If this fails, go to an AASP for service.
My hard drive is out of space...
This is another common issue I encounter...a lot.
- Go to your users folder, right click and select properties. While you are at it, check your Library Folder.
- To check your Library Folder, press Command + Shift + G. Go to ~/Library. Right click and select properties inside the folder. Look at its size.
If your user Library folder is HUGE, then there is only one thing that can cause that: Mail.
- Go to ~/Library/Mail and look for a mailbox that is huge and that has recovered messages in it. If you see one, drop down into terminal.
- cd to the offending mailbox (ex. cd ~/Library/Mail/V2/IMAP-*******.com)
- type ls -la - This command will list all files and hidden files.
- Type du -sh * Look and see how big the folders are inside. If you see Recovered Messages is large
- rm -rf (start typing Recovered and press tab, it will finish the name of the file/folder)
- hit enter
- also remove .mbox.cache.plist
My Mac beeps 3 times and/or has a light that flashes 3 times
This is another common issue I run across from time to time. Generally this can happen after a memory upgrade or is caused by bad ram/ramslot/logic board.
To Do
- Re-seat RAM
- Remove RAM and test each stick individually in each slot to rule out a bad RAM slot
- Replace Logic board - MUST be taken to Apple or an AASP for repair. That is if you get a know good part and know how to take the things apart without hassle *cough* iMacs are a PAIN *cough*
My Mac won't turn on.
This includes, but not limited to:
- No power even after pushing power button
- Can hear fans, no chime, no display
- Hear fans, chime, fans ramp up, no display or Light, chime, no display.
- Light turns on, no chime, no display
- Light turns on, then quickly back off
This can be 1 of 3 things (4 if it is a laptop):
- Power Supply
- Power Button (in a laptop, that means top case replacement)
- Logic board
- Battery (in some cases)
Generally when this happens, you need to take your machine to an Apple store or AASP.
I forgot the firmware password to my Mac! HELP!
Well, this one is easy.
- Turn off your machine
- Pull a stick of RAM out (this changes the hash for the password and resets)
- Do a PRAM reset as soon as you hear the chime. Press and hold the CMD + Option + P + R keys.
- All reset

If you have quesitons, ask and I can help you. Just do a print screen of what you have in terminal.
If your mail is not the issue, then you just got a lot of data. Upgrade time. Or just delete some stuff.
As I remember or encounter issues, I will continue to list them here.
IF you have questions, ask them here in this thread. DO NOT send me a PM. You will be ignored if you do.
