Windows On Mac :: REFIt Freeze - Can't Boot To OSX
Oct 20, 2010I do not have ubuntu, but I have seen people talking about booting with and customizing rEFIt here, and this seems like a knowledgeable place to seek advice. So here's my problem: I have a macbook pro on which I have OSX 10.5.8 and Windows7 x64 (installed through bootcamp 3.1). I downloaded rEFIt and tried to modify the rEFIt interface following the instructions here: [URL] After trying to change the background (hostname.bmg) to a different image rEFIt opened to show the new background (.bmg file) but nothing else (no mac or windows logos like previously) so I can't select an OS to boot to!!
I can still hold down the option key during startup to bring up the regular bootcamp menu which allows me to choose between my bootcamp partition (with windows 7) and what is now called the rEFIt partition (previously called Macintosh HD before I installed rEFIt) So I CAN boot to windows, but cannot boot into OSX without going through rEFIt, which is not showing me any options to choose from. The modifications I made to rEFIt were through the rEFIt.const file in the rEFIt folder in the efi folder on my Mac partition. This const file now reads:
timeout 20
banner hostname.bmp
selection_big selection-big-ring.bmp
hideui tools shell funcs hdbadges label
legacyfirst
I can see and read my mac partition in windows, but cannot save to it to reverse these changes I made to the .const file. I was also hoping that the timeout in rEFIt would automatically talk me into OSX even though I cannot see any icons, but after 5+ minutes waiting on rEFIt nothing happens. Also, I made sure not to list badges under hideui so they should still be shown...........
MacBook Pro :: Lion Freeze On Boot After Ram Upgrade
Apr 25, 2012I have a mid-2010 13" Macbook Pro. I wanted to upgrade to 8G of ram so I bought this: url...When it arrived in the mail I installed it and booted the laptop. The apple logo comes up, the spinner starts spinning and then after awhile freezes. I figured that I recieved bad RAM so I sent it back to apple and they sent me new memory. I installed the new ram and the same thing happened again. Booting in verbose mode (Apple-V) doesn't give anything useful.This time I decided to run memory tests. I booted into single user mode (which sees 8G of memory and works fine) and ran memtest overnight. It ran 6 or 7 passes without finding any memory errors.My next plan is to try to my DVD reinstall/repair the OS to see if that will help but I don't want to do that because I would have to downgrade to Snow Lepoard and then reinstall Lion and that takes long enough to try to avoid.

Intel Mac :: Using External Hard Drive As Both A Boot Drive And Timemachine Backup?
Mar 8, 2012My internal 1TB hard drive on my iMac is dead and I don't have the money to replace it at the moment. I have everything backed up on an external 1TB drive using Time Machine. As a workaround for the time being,Is there any way I can install the system on the external drive and use that as the boot drive without erasing the Time Machine Backups? It seems to me I would have to have two partitions for the external drive, one for the system, and one for Time Machine. But is there any way to add a partition without erasing the existing one with Time Machine only on it?

Intel Mac :: Cannot Boot From Selected External Drive On Intel Core Duo 10.4.3?
May 29, 2012OS X 10.4.3 IMAC Intel Core Duo. I backed up my HD on an external drive so I could upgrade to Snow Leopard. I wanted to test that I could boot from the external drive and selected it as my start up drive. When I did a restart I got the Apple and the turning gear and then suddenly a black screen with this on it:
"May 28 22:23:11 Launched:com.apple.nibindd:respawning too quickly throttling, exited system abnormally bad system call too many failures in succession I have no name!"
I tried several dozen times with no luck. I think when I made the copy of my HD on the external HD I may have neglected to make it "bootable" (moving too quickly). My internal CDROM is busted so I use an external CDROM. I can't boot from it at all with the proper start up buttons pushed. It keeps trying to boot from the external drive. If I turn the external drive off and try to boot from the external CD I just get the grey file with the ? in the middle of it.
I tried using another external HD I have with OS 10.4 on it, but it won't recognize it either with fan, alt, shift, delete pressed at start up. My internal drive (a Seagate 2 tarabite drive) works great, but how do I reset it as the start up drive when I'm stuck with this black screen. One more thing, when I try to reset PRAM I don't get a second gong.

Intel Mac :: Won't Boot From External Drive
Mar 15, 2012Currently I'm upgrading from Leopard to Lion (via Snow Leopard) on both an iMac and MacBook Pro (both Intel), but before I proceed with the OSX upgrade I wanted to back everything up. Thus far I have partitioned an external firewire drive (G Drive - one that is bootable), and cloned each machine using Carbon Copy Cloner to it's own partition (both GUID). There is plenty of space left over on each partition, and is Mac OS Extended (Journaled).
The issue - I can boot the OS X from the external drive on the MacBook Pro but not on the iMac.
When I restart and hold down Option on the iMac the only drive that appears is the HDD, not the other two drives that are visible if I boot up on the MacBook Pro. On the iMac in System Prefs > Startup Disc I can see all 3 drives but when I select it and restart, the machine freezes on the grey loading screen and goes no further.
Not that it should make a difference, but there is a 3rd partition on the external drive that is currently empty (for extra storage).

Intel Mac :: Is It Possible To Strip Down Boot Drive
Jun 29, 2012I have purchased my first Mac Pro.I also am looking at buying a PCIe SSD to use as the home drive (boot). Since SSD drives are a zillion dollars, I can only afford a 120 gb drive. This will hold all my applications just fine, but the issue is with all the "extras" that go with these applications such as:
- Motion media & templates
- DVD Studio Pro templates
- Soundtrack Pro loops and samples
- music files (for iTunes)
- photos (for iPhoto)
- emails (for Mail)
Is it possible to download my OS and applications to the SSD, but route all the extra media, music, photos, emails, etc. to another hard drive? As far as I remember, the OS automatically puts items like the iPhoto library and iTunes music on the same hard drive as the appliciation, which could be a problem if those files continue to grow. Same with the Pro Apps.I don't recall that Motion or DVD SP give you the option of putting the extra media on a separate drive.

Intel Mac :: Can't Boot From External Lion Drive
Mar 16, 2012I am unable to boot lion from an external drive on both a MacBook Pro mid-2009 and an iMac late 2008. Both have lion installed and I would like to boot from either a FW drive or USB key. I have reformatted both a FW drive and USB and set them to GUID and installed lion but I can only boot them to the Disk Utility App (drive shows up only as 'EFI Boot' when I hold option down).
The firmware is up to date and I also reset the PRAM. I am able to boot both computers from an external USB Snow Leopard drive.

Intel Mac :: Won't Boot From Hard Drive Or Disk?
Apr 1, 2012Gray screen and 'prohibited' logo appeared today without apparent reason.Forced a power down by holding power button. Restarted....eventually reached user login screen but froze again on login attempt after password entered.
Restrated again by forced power down but only got gray screen and spinning gear.
Have now spent many hours going through most conceivable options including...
following instructions on http://support.apple.com/kb/TS2570 re gray screen troubleshooting
have disconnected peripherals; reset smu, smc, and pram;
safe boot w shift key did nothing;
safe boot shift+v produced a screen of text that got as far as com.apple.launchd 1
but then several lines of text appeared repeating twice eaxctly same, each headed by disk0s2: I/O error. with [ErrNo 5], then
dyld: Library not loaded: and Reason: no suitable image found
final line ends with The System bootstrapper has crashed: Trace/BPT trap:5
I have tried installing from the original install disk several times but holding C key or Option/Alt key or D key gets no response and I cannot get the install disk to eject either holding down mouse button, eject button
I haven't done any recent upgrades or installed new software, no new peripherals attached.
Is this a dead hard drive or does someone have other suggestions that might work?

Intel Mac :: 27" (2009) Won't Boot OSX From The Internal Drive?
Apr 14, 2012Here's a fun problem. After installing Sophos anti-virus and starting a (VERY slow) full scan, a day or two later I found my iMac frozen at the screensaver. It was completely unresponsive so I did a hard reboot, at which point it got as far as starting to boot Lion (apple logo on screen, spinning indicator showing) before stalling indefinitely in that state with the indicator spinning.
I restarted and booted from the recovery partition, launched disk utility, and discovered that the SMART status of the drive was "failing". The machine would still boot from the recovery partition and my boot camp partition, but I assumed that the disk failing was why the OSX partition wouldn't boot (the recovery partition worked, as did the windows 7 bootcamp partition). I replaced the factory-installed internal HDD with another of the same make, model, and capacity (Seagate 1TB), and performed a restore from the Time Machine backup on my Drobo.
The result was the same as the original problem - it wouldn't boot, hung with the indicator spinning. Thinking that the Sophos scan was somehow responsible (in-progress when the last TM backup was made) I tried restoring to a backup a few days older, (to the best of my recall from BEFORE I downloaded Sophos) only to have the same result.
Anyone have any ideas? I made a clean install of Lion (using the recovery partition on my old internal HDD, now connected externally via USB) to an external drive while I was waiting for the replacement hard disk to arrive, and it boots fine from that. I haven't tried a clean install to the internal HDD yet, as I'd obviously prefer to recover my installed apps as they were before, that being the point of a Time Machine backup, right?

OS X :: External Hard Drive Causes Mac To Freeze / Hang
May 31, 2009I bought a western digital passport hard drive last week. everything was working fine until yesterday. when trying to copy iMovie events to the drive, it hung, and iMovie crashed. Since that time, everytime I try to mount the drive, my finder hangs. I cannot eject the drive properly. I cannot access any old files. I can continue to use other applications, including flock, or tweetie, etc. but can't do anything with the drive.
I have tried searching the forums, (i'm not an advanced user). I have tried using disk utility, and it says; 'The disk ?Murtaza Malik HD? could not be unmounted' When I try to eject it says the drive is in use, and cannot be ejected. I was using the drive with time machine. I disabled that, and now time machine also hangs when i try to access it.
OS X :: Mac Temporarily Freeze When External Drive Starts Up
Sep 24, 2009I have had this problem for some time, on Leopard and on Snow Leopard (don't remember about Tiger), where my mac freezes for 2-5 seconds when my external drives are woken up. This happens often when I access the "file open" window, it will just sit there until the drive is started.

View 7 Replies View RelatedHardware :: External Drive That Doesn't Freeze Up System?
May 26, 2009I have 5 external drives... They are Seagate and Western Digital Drives. The worst of the bunch is the Western Digital My Book Studio Edition (1TB) that I have connected via FW800. The 2nd worst offender is the Seagate 750GB Free Agent connected via FW400. The most dependable appears to be a Western Digital USB drive, but it's the slowest performer. The issue is this: I either have a freeze up that requires an unplug from the Mac as well as power, then re-mount to get working again, OR, when I start up the Mac, it just hangs at the 'apple' and never fully boots. I have to unplug the drives and boot, then plug them back in after the boot. It's getting very frustrating. Do you all have a successful setup with external drives?

Mar 13, 2012On my late 2011 imac 21.5" I have been getting a consistent problem since the last OS update. After the screensaver comes on, or, if left to sleep by it's own devices, either my screensaver freezes or the gray screen won't recover from sleep. If I move the cursor with the trackpad it clears the gray screen where the cursor moves around. I can usually clear enough that I can hit the login button and log in after pushing the power button. This is a new phenomenon since the latest OS update.

Intel Mac :: Applications Freeze When Left Idle?
Feb 27, 2012Since the recent software update (early Feb I believe) my Mac has begun to freeze, first finder, then safari/chrome, followed by all other applications.
I have set up Activity Monitor to track what is causing the issue, however when the computer freezes I cannot open Activity Monitor (obviously).
I have contacted Apple Care with the hope that they could provide some assistance, we deleted all startup files (and the other startup related files in library), ran disk utility and repaired permissions.
We noticed that spotlight was using a lot of the CPU, and I removed my external time machine harddrive (as it appeared that it was damaged).
The freezing still occured, so I reinstalled Lion. The computer appeared to be working again... until it began to freeze again.

Intel Mac :: Why Does It Often Freeze After Turning On From Sleep Mode
Apr 28, 2012I've been using Pc's for the past 30 odd years so am totally new to Mac. I'm doing my best to adapt to this new different OS and so far have found some things more user friendly but others ? I've more or less given up on those as Mac doesn't seem to do those things. These are probably Windows based and I'm assuming Mac has its own alternatives that I haven't discovered yet. Anyway, my immediate problem is this goddamned frustrating situation when I try to re-activate the comp' after waking it from 'sleep'. Sometimes its fine but others, it comes back on but freezes and the only option I have is to turn it off at the switch and do a re-boot!
