The idea for this quick GUIDE was thought up in this thread by kingjr3. Like the networking thread the idea of this is to have a quick point of reference for those common questions. How to Zap PRAM Zapping PRAM is simple, just reboot your Mac and hold down "Command(the Apple key)+Option(the Alt key)+P+R" while it is booting, when you hear the startup sound for the seond time the operation is complete, and you can release the key combination. Now just let your Mac boot as normal. How to Repair Permissions
- Navigte to "Applications > Utilities", and open up "Disk Utility".
- Select the volume where your OS resides, and hit the "Repair Disk Permissions" button.
If you are comfortable with using the Terminal (Applications > Utilities > Terminal.app), you can also enter this command to run repair permissions - "sudo diskutil repairpermissions /" (without the quotes), just enter your password when prompted. How to run FSCK
- Restart your Mac holding down "Command(the Apple key)+S" key to enter 'Single user mode'.
- Type "fsck -f", and hit return.
- Once complete type "reboot" and hit return to reboot you Mac back in to OS X as normal.
If there is anything that you think is wrong here, or you think I have missed any vital steps out, please post and let me know so that I can ammend this.
Disk Utility says there are a bunch of disk permissions that need repairing. I hit repair and disk utility says that it repaired those disk permissions. But when I verify, it says they still need to be repaired.
When running Repair Permissions in Disk Utility, it reports that there are errors and that it's fixed them but if I run it again, the same errors keep appearing.
I've noticed that the current permissions on the errors are lrw-rw-rw- which I assume means that they are symbolic links and not the actual files which Disk Utility is expecting. Any idea what's going on?
Problem: MBP frozen on boot up screen with Apple logo and turning gear (which freezes after a while aswell)
Solutions attempted: disk repair via custom recovery- disk utility, PRAM
Device: MacBook Pro 15" (early 2010) running 10.9
Never had any issue with the device and this seems to have happened all of a sudden. Installed an SSD a few months ago, and just realised the ssd did not have a recovery partition. However I connected my older hardrive via USB to access recovery which seemed to work fine.
NOTE: for the past few weeks, every now and then I was unable to power the device off and whenever this occurred, there seemed to be a few bugs (ie unable to empty thrash-error 50 and enable to increase/decrease volume/screen brightness). However, holding the power button and restarting it seemed to have fixed it.
Had the same issue but this time around MBP failed to boot up.
What are all these errors, i did a repair permission before software update to 10.5.6, than i restarted and did a repair permission after software update and now for the first time i got all those SUID errors.
Yesterday i checked my hard-drive for permissions and it found ALOT it had to repair, so i repaired them and all went fine. Then i restart check again LOADS more!!, if i repair and even wait 5mins loads more come back instantly why this could be?
Also could this be a reason for why when i now start my MBA it seems to hang on the grey screen before showing the apple logo and starting to log me in?
So my teacher's iMac is behaving weirdly. She turns it on and she is asked to type in the password to log in. It's not set as automatic login. But it says the password is incorrect. She is positive the password is typed in correctly. She reboots it and types in the same password. This time, it lets her in. I tried repairing permissions but to no avail.
i have a problem that everytime i restart my imac (late 2007) i get the blinking folder for 15 minutes up to a couple of hours then it starts up normally. i tried clearing up the PRAM. reset the SMC. and it still happens.i tried to do from the system a repair disc permissions and i got back one error that cannot be fixed which was
<quote> Warning:SUID file"System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents?MacOS/ARDAgent" has been modified and will not be repaired.</quote>
i have even tried to fix the error from the bootable CD, but same error. i even upgraded to snow leopard but no apparent change. i dont even know if this is the cause of the problem. but all other stuff is OK. even the boot CD hardware thorough check was all ok.i still get some noise of the fan when i boot up for a couple of minutes then it goes away.but temperatures are quite good and fan speed is around 800rpm at the moment and no sound is to be heard.
I have a number of files that have been modified and are SUID files that will be repaired by Disk Utility. Anyone have any idea what this is or if you are seeing this with your Disk Utilities... Here is the output...
Repairing permissions for ?Macintosh HD? Warning: SUID file "usr/libexec/load_hdi" has been modified and will not be repaired. Warning: SUID file "System/Library/PrivateFrameworks/DiskManagement.framework/Versions/A/Resources/DiskManagementTool" has been modified and will not be repaired.................
A couple of days ago I did a software update for the airport I believe. Everything went fine during the update and after. Every once in a while I do a permissions repair to do some maintenece. I just did it and it repaired prob like 20 entries. All the entries said airport in it. It did repair all of them though. I re ran it and none of them showed up again. So it seems fine. But just curious why it would do this, kinda odd?
When I open Disk Utility and select one of the 2 volumes in the left pane, the buttons "Verify disk permissions" and "Repair disk permissions" remain greyed out. Only the "Repair disk" and "Verify disk" buttons are enabled. This is not the startup Volume. For this volume all 4 buttons are enabled.
How can I repair the disk permissions on the volume?
Right, I just upgraded the Hard Drive in my white Macbook today. So I put a fresh install of OSX on and put all my pictures, music, apps etc back on. After I had done everything I decided to check the permissions and repair any if needed. As it was verifying the permissions loads came up that needed repaired. So when i clicked repair it all seemed to go fine, it doesn't say any couldn't be fixed or nothing. But I went to verify them again just to double check and they were all still there needed repaired again.
i need help with my macbook. I just updated the Leopard 10.5.7 and something is up with my machine.It has randomly been hanging and freeze my mac by telling me i have to restart the computer. Its happened about 5 times now!
I tried repairing permissions but everytime it does i have something that cannot be repaired for some reason. Could someone tell me what is happening and why my permissions arn't being repaired...
Recently I archived and installed leopard from tiger. Since then sometime there is a message that comes up telling me I need to restart my computer in all different languages. Also when I try to verify and repair my disk permissions, this is what shows up: Permissions differ on "System/Library/CoreServices/Front Row.app/Contents/CodeResources", ....
I am a Mac veteran and should know better but I went brain dead and rebooted system after an update while the repair permissions function was running in the background. Now my IMac will reboot and then start to load once I login but it hangs on the startup screen only showing my mouse arrow and the standard space startup background. It won't get to my desktop. Am I going to have to reinstall the system? I have everything backed up on Time Machine but I can't access it from this position. I have a project I have to finish tonight and now I'm really screwed if I can't get in it.
I bought this G5 with consistant startup problems but after replacing the hard drive,installing a fresh operating system, re-seating the ram, checking the Pram battery, etc, it was running fine. I now realize that when trying to repair the disk permissions, the same list keeps coming back even though it shows it's been repaired. Also, occasionally it may freeze or go into kernal panic on startup. If the hard drive is new, does it sound like a possible hardware problem? Does repairing disk permissions involve anything hardware?
