Mbp 10.4.8. Grey logo like tiny ghost page follows arrow, then freezes up! Tried reformat hw test. got nowhere! Any help?
Used mbp for 4 years with no problems at all, but recently had a screen freeze, and noticed a a small icon under the pointer. This was like a tiny greyed out page of type. Re-booted and got grey screen + wheel, but then blank blue screen. Had to soft boot but still got tiny page following pointer. Re-formatted entire system and OK for a few minutes but then page returned along with freeze-ups. Ran the hardware diagnostics from first disk but said no problems at all. Has anybody else come across anything like this? Grae
Okay, so this is what I've heard about RAM and problems after updating. I recall from somewhere in these forums that RAM can be totaly fine until you do things like install a program, update, or do something you havent don before. If memory serves me right, these things can lead to kernel panics and freezing because you would be accessing parts of your sticks that you never would have before, thus, never having it detected as bad. As for basic issues with it, RAM can go bad over time; this is when you need to contact the original company you got it from. And from my experience... Apple tech guys are probably really bored and end up reformatting everything I send in. I would just say leave the messed up one out of your computer. 1G is definitely enough to get by until you return to your apartment to argue with Apple phones for the next X number of straight hours :P. I mean, if you ARE doing heavy workloads involving a lot of ram, I'd still leave it out because Id rather have my work finished cleanly but slowly than at a high risk of crashing and needing to start over again.
PS. with the hardware test for RAM, I've also heard on these forums that it doesnt test the RAM that the computer is using to run. So maybe if you put both in and switched them around, it would allow it to access the bad segments

I'm getting 100s of debug.log. files on my macbook OS 10.7.5. I've never seen them before. Should I be worried? They look like this: debug.log.100100_100119.sent. Is it an encryption problem? thanks for any help!

Hi I'm using a Mac Book Pro with a separate apple keyboard (wired). Randomly the keyboard will make a thudding noise like a key is depressed and stuck (which it isn't) which then stops when the keyboard is unplugged. I've tried rebooting, plugging it into another port and unplugging my mouse from it and it hasn't solved the issue. I also can't pin point when it does it, it seems to be random so sometimes, like now it's fine and then others it does it every few minutes. I'm reluctant to throw the keyboard out if there is a chance it can be fixed. Any ideas?
You cannot use any additional devices on the keyboard's USB ports when used in this fashion (except perhaps ONE low power Apple mouse). Anything more draws too much power and may make the keyboard malfunction. In general, keyboards do not tend to complain about low power, they just stop working properly.

water damage iphone 4 was coming on when plugged in but not charging and not holding any power so changed battery it then worked untill battery power ran out and would not charge so changed the docking port and now it comes on with apple symbol and switches back off after 10 to 15 seconds like its rebooting and then just keeps repeating any help please
Help with what? Apple does not repair iPhones, they replace them. Apple does not sell parts. There are no legitimate sources for iPhone parts.
Talk to whoever did the initial repair. Odds are the logic board is damaged. It's probably time for a new phone.
Your phone is no longer eligible for a discounted out of warranty replacement. -
This is happening on a brand new 21 inch imac, all new specs released a few days ago.
This happened the first time I started up the imac straight out of the box. The screen displays alternating light and dark grey bars with green pixel specs all over it. The apple symbol and and loading symbol are visible too - but it then goes to a light grey screen and freezes.
If I manualy restart it will then startup normaly but will do this next time I startup the machine from a cold start.
Does anyone else have this issue. This is my first mac and it doesn't seem acceptable to me. I think I've been sent a dud!
Any help / opinions would be helpful. CheersI wouldn't try to solve this issue by troubleshooting a brand new machine. My personal policy is if an electronic device is malfunctioning out of the box, I return it for a replacement. We're talking about an expensive purchase and it should work, but even with stringent quality control a small number of products will fail out of the box. You didn't mention whether you ordered it online or purchased it at an Apple store. If you can, get a new machine at an Apple store and take advantage of the free setup. An Apple salesperson will start it in the store, so you'll know before leaving if it's good.

I have lots of photo albums on my iPhone. They came from my computer. I'm never given the option to delete these albums - I can tweek them or send them, but no delete - not even the individual photos. I no longer want these - and I no longer have these on my computer. I understand that I can't transfer back to my PC, but I would think that I could at least delete them off my iPhone.
Did you try unchecking Sync Photos on the Photos tab of your sync settings and syncing? If this doesn't remove them, try creating an empty folder on your PC, then selecting to sync this folder on the Photos tab and syncing your phone. This should delete the existing photos prior to syncing the empty folder.
Also, you can transfer these photos to your computer if you need to by using an app like PhotoSync. -
My iPhone 4 has been disabled and it went to the "Connect to iTunes screen."
At first, iTunes told me to unlock the phone before I could use it in iTunes.
Until, I turned the phone off, pressed and held home while plugging the USB cord back into my device and now my phone is at the "Connected to iTunes screen."
However, it is not coming up in my iTunes and I have no idea what to do.
If there is anyway that any of you know how to keep all your data but restore or reboot your phone, I'd love to hear from you.
Regardless, I need to undisable my phone!! HELP! Please and thank you!You need to force the phone into recovery mode, as described here, & restore it:

Sorry, you've already lost all data on your phone. -
I have a lot of books on my Kindle/Amazon account. I have downloaded the Kindle app onto my IPAD mini by can only access my books when connected to WIFI, how can I read them off-line?
Yes, you've missed the download step.
Open the Kindle app and navigate to your Library. There is a tab at the bottom that says Cloud | Device. Tap the Cloud tab and tap the books you want to download to the device. You will see a progress indicator during the download. Once it's done, read away! -
Problems installing OS
I have an iMac 21.5 (mid-2010) and I'm trying to install a new hard drive. When I choose the installation disk the Apple logo comes up and it stops there. Then the mouse and keyboard goes dead. I'm trying to install 10.6. Any help would be appreciated. ThanksSince you have a new hard drive, there is nothing on it, so you need to boot from an external source (and probably format the hard drive before installing an OS). Are you booting from the 10.6 install disk? Better yet - do you have a bootable backup clone or at least a Time Machine backup?

Hello my MBP 15" stops at grey screen after apple logo disappears
hello, my MBP 15" stops at grey screen after apple logo disappears, what can i do about this? ive tried booting into safe mode but screen turns blue with black lines also tried resetting NVRAM and PVRAM but still stops at grey screen, also tried using applejack, it shows no problems at all, says my disk volume is ok but the screen still stops at grey during start up, havent tried the installation disk thing because i dont have my installation disk with me
Take each of these steps that you haven't already tried. Stop when the problem is resolved.
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.”
b. 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.
c. 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 either of the techniques in Steps 1b and 1c 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 you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
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, 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. 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 10. 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
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 10
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 11
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 12
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. -
Won't boot past grey logo screen
I have a refurb dual 2Ghz powermac G5. New in March 2006.
It will not boot past the grey logo screen. I have tried all of the regular stuff: reset pram, reset nvram, reset-all, pushed the PMU button, etc, unplugged; reset ram; removed and reset ALL cards/memory. And nothing.
When trying to boot in single user mode, it freezes when almost getting to a prompt.
I CAN boot to open firmware. Though booting from the OS X install cd yields the computer to freeze at the grey logo screen.
I am dual booting Gentoo Linux, and the curious thing is that if I select Gentoo at boot, the computer freezes when loading the kernel for Linux.
So it's not an OSX thing it seems like; probably hardware.
I ran the 40min extended apple hardware test from the PMG5 OS X disc which passed everything with NO errors.
I then booted the disc in target mode with my iBook, and repaired permissions: it said was all okay, nothing to fix.
I removed the battery, and placed it back in. The battery tests fine with my voltage meter-tester.
I am a PC technician, but am stumped in trying to get my powermac to boot. Let me know if you have any other ideas. Thanks,
Dual 2Ghz Powermac G5

Dual 2Ghz Powermac G5 Mac OS X (10.4.6) Logic 7.2 Gentoo PPCOkay my powermac is at the local mac repair center. All hardware checked out okay; the tech is unsure of the issue. He's pulling parts and going to see what part is failing. He thinks the power supply is freaking out and sending out too much voltage, causing the computer to freeze at boot.

IMac won't boot past grey logo screen
20" iMac was acting very slow, to the point where I would get the rainbow ball if I opened the HArd Drive icon.
Revolted but couldn't get past the grey logo screen and spinning wheel. Tried a Disk Repair from the Snow Lep disc but it just froze up.
I restored from my Time Machine drive and 24 hours later it's still the same. Getting ready to bring it to the genius bar unless anyone has an idea!HI Rob,
Check to see how much space is available on the startup disk. Right or control click the MacintoshHD icon. Click Get Info. In the Get Info window you will see Capacity and Available. Make sure you always have a *minimum of 10% to 15% free disk space at all times.*
If your iMac freezes before you can view that information, boot from your install disc like you did with disk repair only this time look at the bottom of the Disk Utility window. You'll see Capacity and Available.
Since you can't boot from the install disc, you could try booting in Safe Mode
If you can boot into Safe Mode, launch Disk Utility from the Applications/Utilities folder. You can verify the startup disk in Safe Mode, but you can't repair in Safe Mode but at least you'll know if there's a problem with the startup disk.
