View 1 RepliesI'm trying to boot up my late 2013 15" MBP (shipped with Mavericks) using an external startup disk running Mountain Lion. I really need to use the FCP iChat Theater feature, as I need to do some long distance editing. The startup disk works just fine, I checked it on another computer, but when I restart my Mavericks mac and choose it as the boot drive, I just get a grey screen with the universal "no"symbol (circle with a slash through it).

View 1 Replies View RelatedI have a new MacBook Air running Lion. Every time I use my backup software, it changes the permissions on my external drives, and I have to change them from read only to read & write, so I've gotten in that habit. At one point, I noticed that the permissions on my internal *startup disc* were read only, so I (foolishly, I now know) changed the permissions on the startup disc to read & write, with apply to all enclosed items checked. As I continued working, I got messages that a number of extensions could not be used and will be disabled (or something like that). I decided to reboot, so the computer could reset and hopefully correct things.
When I tried to boot, it hung up on the grey screen with the Apple logo and the spinning clock/gear. I let it spin for a while, then forced power down and tried to boot in safe mode. The progress bar appeared as it's supposed to, but when the progress bar finished, it went back to the grey screen and hung up again. I let it spin for over 40 minutes before powering down, just in case it was doing diagnostics or something. I don't have access to the original OS DVD (nor do I have an optical drive to put it in). Any way for getting the computer to boot, at least in safe mode?
Im trying to reinstall osx from my flash drive. The problem im having is after i hold option and click on the flash drive icon to boot it, nothing happens the arrow icon greys out like its being click, but it does nothing.

I 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).Â
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.

I installed Lion on my Intel iMac (about 3 years old) several months ago and it was working fine. Then yesterday it stopped booting up. It loads a grey screen and then just shows an icon of a folder with a question mark in it.

I recently reinstalled a clean Tiger on my old MDD G4 with the intent on giving it to a friend of mine in Oregon. Everything was smooth here in Los Angeles. Got the OS on and running sweet... 10.4.11 combo update... all's well.
I drive up to Oregon, set it up in his office using his old CRT monitor and power it on. It chimes and manages to find the Tech Tool eDrive recovery partition, but not the OS on the boot drive. Then, seconds later, screen of death/kernel panic and no boots or startup chimes thereafter.
Steps I've taken:
I have reset the PMU
I have removed all peripherals, including viddy, SATA adapter and all but on stick of RAM
Tried every stick of RAM by itself
No startup chime -- just a fan for a few seconds then a super fan kicks in... no signal to monitor at all.
Strange symptom: at times power was making it to the drives, and other times not. (determined by me putting my hand on the drive to feel its vibration or lack thereof during boot).
Do I need a new PSU? And if so where to buy?

I am trying to find a way to have my computer automatically boot into the Startup Manager by default. Right know I know you can set it to boot into Verbose, Debug, Single User and Safe mode with the nvram. But is there an option to set it to the Startup Manager.

View 3 Replies View RelatedI have a Mid 2011 13-inch MacBook Air. My speakers chime perfectly at boot up, but then when Lion 10.7.4 loads, it won't load whatever driver is needed to run the speakers.Â
The really weird thing is that I have the speaker icon on my top bar and "Internal Speakers" are not only listed in the Outputs of my Sound tab in System Preferences but even selected. Both the volume bar in the Sound tab and on the top bar are grayed out and non-adjustable. But whenever I reboot, I get a lovely chime sound again.Â
This seems to be purely a software problem, but I didn't even know Mac OSX could recognize the internal speaker hardware without loading a driver for it!

We have an older model G5 Dual (no Intel Core) at the office that we tried to install CS3 on. I told them that first we would need to upgrade from 10.3.8 to 10.4.10, which they did, and then installed CS3. But they did it without running the disk utility repair permissions after the OS software installation, as I have routinely done with my Mac Mini at home, after the horror I experienced with the 10.4.9 upgrade. For a couple of days, the computer ran fine, but I noticed an increase in the fan spinning up yesterday afternoon, then quirky keyboard things -- like I'd select an item with point and click, and it would highlight everything else near it, I'd go to quit an application and it would ask if I wanted to quit all applications.
After backing up my current InDesign work files on a flash drive (but not the whole darn art folder), I rebooted and it came up in Safe Boot mode 6 times without holding any key down. Attempts to boot from disk have failed, even with holding down the "C" key. It's also not allowing us to type out full passwords at the log-in screen... you start typing and after you hit four digits, it clears, then only allows two digits. How we can:
1.) Force boot from disk, and,
2.) Hopefully fix with disk utility whatever wonkiness is occurring?

I need your help please. It all started when I was trying to install Windows XP under Boot Camp on my Macbook Pro (Leopard). I followed the manual and made the partition for Windows (32GB), but when I inserted Windows XP Install CD and had to choose partition to install it on, there was just one that seemed to be my Leopard startup disc (it had some 120GB). I did not know what to do, so I just left the installation process and the notebook restarted. When it loaded, it was trying to boot from the Windows CD so I tried to install it, but same problem appeared -> restart. I tried to load Leopard by holding Option key while loading, but only options for windows and windows cd appeared, no Leopard -> Shut down. While booting, I force-ejected the CD by holding down trackpad button -> blinking underscore on black screen appeared. I shut the MBP down by holding power button and inserted Leopard Install CD. When it loaded, I booted from the CD by holding Option key. This time I was ready to even re-install Leopard just to make it work but when I had to chose the harddisk to install Leopard on, there was none. It seems to me that somehow nobody can see the harddisk and I have no idea what to do with it.

View 4 Replies View RelatedI am having troubles booting from the Mac OS X Install Disc by holding down the "c" key at startup. Can I change the startup disc in Leopard to the DVD and then change it back to Macintosh HD after I am done doing what I need to do with the disc (no, not a reinstall of the OS). Is this possible? Will it work?

View 20 Replies View RelatedIs there anyway to make it always boot to the startup manager. Then maybe after 30 seconds or so it would default to os x. I'm constantly having to switch between OS's and it would be nice if I could make it so that it would auto pop up startup manager rather an me have to hold down the option key every time.
View 1 Replies View RelatedI moved over to an IMac from windows about 2 years ago and have never had any issues, until now. Whenever I boot my IMac I get a 'kernel panic' message (grey screen with 'you need to restart your computer in 4 languages). I cannot boot from my Mac HD, nor from a bootable superduper backup external HD, nor from my orginal SL or Leopard disk. All go into the kernel panic. I can however boot from my bootcamp Windows Vista partition. Tried booting into safe mode also does not work and gives the kernel panic screen. I have run both the standard and extended hardware tests and both have no errors. I booted in single user mode (that still works)and done a fcsk and unmount and both are without errors. Also done RAM flash. In single user modei can not find a PanicReporter directory or panic log. Cannot even install a fresh SL copy as my DVD wont boot either.
View 3 Replies View RelatedYesterday I was helping someone getting to know their MacBook Pro (early 2008, Intel core 2 duo 2.4GHz, Mac OS X 10.5.2). I installed Perian and Flip4Mac and Firefox 3.6. I also checked for updates because she's on a very old version. I tried downloading the updates, but because we had a very bad internet connection I stopped the download quite early on and told her to do it at home. However after I left she tried to shut down the computer but it hanged. She manually shut it down using the power button. When she tried to turn it on again she got a kernel panic message saying she should reboot. This however didn't work.
Now I've tried all sorts of things. I've removed Perian and Flip4Mac manually. I did a disk verification (all was well) and a permissions verification and repair. I tried booting in safe mode (still won't boot) clearing the SMC and resetting PRAM, none of it worked. I just wanted to check here first before either taking it to an Apple store or reinstalling Mac OS X. I've read on forums about hardware failing (RAM mostly). No idea if that's the case. I tried a hardware test, but I don't have her DVDs and used my own with version 10.5.5. The Standard test said it was all ok, but the extended test seemed to hang. I could ask for her own DVDs which I will need anyway if I'm going to reinstall Mac OS X.
Some details of the kernel panic:
The error code is: 0x000000010
Apart from that it says the following:
Backtrace terminated-invalid frame pointer 0
Kernel loadable modules in backtrace (with dependencies):
com.apple.driver.AppleIntelCPUPowerManagement(76.2.0)@0x2e63c000->0x2e65afff
And later on it says: Mac OS version: Not yet set.
And of course it shows some more info with lots of hex codes, I can type them out for you if you like, but I read elsewhere that the error message is usually not very useful. Would you recommend going to an Apple store to see if the RAM is faulty? Or do a reinstall of Mac OS X?
I have a mid-07 Santa Rosa MBP. When I turn it on, nothing comes on the screen (not even backlight), but I'll hear the startup chime and 2 seconds later, it reboots and does the same thing. Here is what I have tried:
1. Reset SMU
2. Reset PRAM
3. Replacing HD
4. Replacing PRAM/CMOS battery
5. Tried booting off DVD (but it reboots too fast after the chime)
I am having a problem getting my G5 to boot. Half the time when I turn it on I get no chime. The other half, I get the chime but the boot process does not continue. If I leave the computer on the fans begin to progressively get faster and louder after about 5 minutes. I've tried starting with various USB and Firewire components unplugged and have even gone to just a keyboard and mouse. No change. Can I get the computer to boot from an OSX CD? How do I open the tray? etc.

I partitioned windows XP onto my Mac HD a few days ago. It worked beautifully until last night. Whenever I booted to it, it stuck at the welcome screen for 10 minutes, and was really buggy upon startup. This morning, my MacBook Pro (bought in August '09) upon turning on automatically boots to windows XP. No amount of holding "c" or "Alt" will bring up rEFIt or boot camp selection pane. And the kicker is, the windows XP partition is completely corrupted.
Here's what happens now:
1) Turn Macbook Pro on, hold down "c" or "Alt"
2) White background for ~ten minutes, nothing happens
3) After a long time, boots to black screen and says "Startup Disk Error... Press Ctrl+Alt+Del to restart.
I'm pretty sure its trying to boot to Windows XP partition, because Ctrl+Alt+Del is not a Mac OS X command... But I can't boot to my Mac OS X partition.

View 6 Replies View RelatedI have a mac pro running leopard (purchased in 2/08) and it was running beautifully for almost 2 months with no hangs, crashes or freezes. Then, for some reason, today when I turned it on, it would not boot. It would get to the apple logo, then just sit there for a few minutes, then reboot itself and the same thing would happen. I pulled out the ethernet cable, unplugged all usb except keyboard/mouse and it would then (sometimes) boot into the system, log me in and present me with the UI.
I then quickly performed a soft reboot and it would get to the desktop. However, I can only use it for anywhere from 30 seconds to 5 minutes before it would completely lockup. The clock freezes, the mouse freezes and it just sits there forever. I have tried booting into Vista (BootCamp) and it also freezes before startup is complete. If I hold down Option and then select the System disk, it will either just hang forever or get to the desktop and then freeze again....................
just using my new MBP today and twice when turning it on it started to boot up and got as far as the blue screen (just before the desktop pic and stayed there.Is this normal sometimes?
