Failed ? install of 10.8 -safe mode extremely slow
hi this is my first post here
i have an imac early 2009 core2duo 2.93 ghz with 8gb ram ( it came with 4 but i upgraded with official apple ram - took it to an authorized reseller .
( i 'm in greece and we do not have an apple store ... yet )
anyway i was running 10.6.8 and it was fast but i decided to upgrade to mountain lion
i used a usb stick to format since the imac had a kernel panic and was unable to create a second partition for dual booting ( i was planning on installing 10.8 on a second partition just to test before updating Macintosh HD )
so i formated
it installed and said installation succeeded BUT when it restarted after the boot chime and the apple logo and the wheel the desktop did not show up . just a blank screen . white .
then apple support told me to format again with the snow leopard dvd and redownload 10.8 from the mac app store and update . did all that ( disk newly formatted ) same thing happened .
after the installation suceeded message your computer will restart in 5,4,3,2,1 it restarts and boom no desktop
apple support told me to start in safe mode and it booted . but it is extremely slow . laggy . like windows with a virus
activity moitor ( i barely managed to open it ) said cpu 97% usage and ram 7.00 gb + used
is it normal for safe boot to be so slow or my imac cannot run 10.8 ?
it's a core2duo 2.93 ghz as i mentioned
and i upgraded the ram to 8gb just for the update . .
in the authorized apple service they told me it's probably the hard disk but the support phone line sais probably sth with the graphics
both agree : hardware issue ...
it's a pitty they removed lion from the app store . i could format back to snow leopard download lion ( which i bought but never installed ) and then update to lion .
i do have a bootable dvd created from the InstalESD.dmg file of lion . i also have a copy of the installer on my external HDD .
would it cause more trouble if i used the lion dvd i created boot from there format , and then choose reinstall mac os x ... then see what happens ?
maybe it's just m lion that causes the problem ?
and and another thing . if it is indeed a harware problem wouldn't i encounter the same issues on snow leopard when i formatted and came back to it from M Lion ?

IMac works fine in safe mode, extremely slow in normal mode
Hey guys, I'm going nuts!
My mac got stuck on a white screen, I ended up reinstalling Snow Leopard - now when I boot in normal mode everything is extrememly slow - when I mouse over the corner of a window (close minimise etc) is stops and takes about 10 seconds to make the rollover affect (putting the "x" in the red circle). When I move the mouse over anything on the desktop, it stops working for about 10 seconds as well. The mouse moves around the screen fine, and after a lot of painful (and very patient) clicking, I can transfer files around fine - happens just as fast as it would normally, windows open as normal etc.
The most frustrating part is - everything works fine is safe mode! I'm typing this message on the mac now... I was thinking that I could transfer all of my data on to an external drive, but safe mode won't recognise them it took me about 10 minutes to select a folder and copy it to a hard drive in normal mode - I can't drag over a few items because of the mouse problem...
I have updated my software - can't open the app store for some reason (I want to upgrade to Lion as well). No idea what to do...One of the primary difference between a safe boot and a normal boot is that all third party software is prevented from starting in the safe boot. So it sounds like something you installed on your Mac is causing the problems.
Are you running any kind of AV software?
If you are I would suggest that you start by unsintalling it. There are no virus on the Mac for the AV software to find any way so all it ever does is cause problems.

OS X Mavericks installations fails after reboot, stuck. Safe mode does not help
Quick Summary: Installation of Mavericks gets stuck after reboot, no safe mode boot, only recovery console works.
Update: Currently following procedure http://support.apple.com/kb/TS2570?viewlocale=en_US
I have upgrade 4 out of my 5 machines, but the most important iMac 27" mid 2010 went through with the installation and then got stuck on a grey screen with the apple logo and a spinning wheel for 6 hours.
A few restarts did not help.
Started from recovery a new download and install. But it ended up in the same end.
Trying safe mode/boot, but does not finish
Going back to recovery and try repair disk, does not help
Going to recovery using terminal resetpassword and then setting the permissions for all login accounts back, no good.
Going to recovery and using terminal to check /var/log of the mounted Macintosh HD.log shows at the end "The installation was successfull"
System.log shows
com.apple.kextd: Failed to send personalities to the kernel.
Error: Couldn't send kext personalities to the IOCatalogue.
Exited with code: 71
Throttling respawn: Will start in 8 seconds.
Resetting NVRAM/PRAM and reboot, waiting so far stuck but I still hear some disk activity, waiting a little bit longer.
Any help?Do you have a Recovery HD from your previous systems?
Boot Using OPTION key:
1. Restart the computer.
2. Immediately after the chime press and hold down the
"OPTION" key.
3. Release the key when the boot manager appears.
4. Select the desired disk icon from which you want to boot.
5. Click on the arrow button below the icon.
Look for another Recovery HD, although you need the OS 10.9 one if it's available. If it's not, then you will need to start over from scratch by erasing the drive then reinstalling 10.9.
Install or Reinstall Mavericks, Lion/Mountain Lion from Scratch
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Erase the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your startup volume (usually Macintosh HD) from the
left side list. Click on the Erase tab in the DU main window.
3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on
the Security button and set the Zero Data option to one-pass. Click on
the Erase button and wait until the process has completed.
4. Quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Install button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible
because it is three times faster than wireless. -
Can only start Windows 7 (installed with bootcamp) in safe mode
I installed Windows 7 about 3 weeks ago, everything has gone smoothly until a few days ago. I can only start Windows in safe mode, if I try to do it in normal mode, it starts to log in but the screen will just go black and the computer will shut off completely. Then it won't turn back on for like 5 minutes. My mac partition works fine, and I can't find a solution to this Windows problem. When I try to do the "restore' thing where you make it go back to a certain install point, it gives me an error. Please help me, I have a course starting in 3 days and I need Windows OS for it.
Post your question in the BootCamp forum.

How to install Windows Updates in Safe Mode with Networking
On my VISTA Business edition, I was getting BSOD (blue screen) so I booted the system in Safe Mode with Networking. But in this mode when I go to Start Menu-->All Programs-->Windows Updates, nothing happens. Please help.
Thanks..Namhttps://www.youtube.com/watch?v=rMDjZQqz-i8
Steps:
1-Open command prompt with admin mode
Or Boot from DVD in command prompt mode.(This is what i experienced, able to show the safe mode menu)
2- Write this command "bcdedit /set {default} bootmenupolicy legacy" and click enter
3- You can now press F8 while Windows 8 starts in order to access Safe Mode and other Advanced Boot options. -
anyone else have the same problem? and if so, what is being done about it??
Back up your documents and everything else important to you, not that there is any reason to believe your hard disk may be failing, but the symptoms you describe may presage an impending disk failure, and you should have backups anyway.
To help determine the possible causes of this behaviour read the following. None of what follows is intended to fix anything, but it will provide the additional information required to advance troubleshooting:
Boot OS X Recovery by holding ⌘ and r (two fingers) while you start your Mac. For Snow Leopard, start your Mac while holding the c key with its original OS X Install DVD inserted in its optical drive. At the Mac OS X Utilities screen, select Disk Utility. Select your startup volume (usually named "Macintosh HD") and click the Repair Disk button. Describe any errors it reports in red.
When it finishes restart your Mac and test again for operation. If it's still not behaving as you expect it should, please post the results of EtreCheck in accordance with the following instructions:
Apple Support Communities contributor etresoft wrote a very useful app to quickly gather certain system information that may help point to a cause of this problem. Go to his website, download and run EtreCheck:
http://www.etresoft.com/etrecheck
Etrecheck will be in your Downloads folder. Open it from there. You may see the following dialog box:
Click Open - etresoft contributes to this forum frequently and can be considered a trustworthy developer.
It will take a moment to run as it collects its data.
Copy and paste its output in a reply.
Do not be concerned about anything that says "Problem" or “failed” or anything else that may appear in red.
EtreCheck was designed to remove any personal information (such as your computer's name and serial numbers) but if you see anything that looks like an email address or any other personal information that should not be divulged to others, please delete or obscure that information when you post the reply.
When you are finished with EtreCheck, quit the program. It occupies very little space, and you can keep it or drag it to the Trash as you wish.
After completing the above please determine if the problems also occur in "Safe Mode":
Safe Mode or "Safe Boot" is a troubleshooting mode that bypasses all third party system extensions and loads only required system components. Read about it: Starting up in Safe Mode
Starting your Mac in Safe Mode will take longer than usual, graphics will not render smoothly, audio is disabled on some Macs, and some programs (iTunes for example) may not work at all.
Merely starting your Mac in Safe Mode is not intended to resolve the problem, it's to observe its performance without certain additional components.
To end Safe Mode restart your Mac normally. Shutdown will take longer as well.
Some users have reported an SMC reset to be beneficial. Be sure to read the procedure carefully and follow all the steps exactly as written, even if they seem inapplicable or trivial. -
It's only the first screen/tab I open after firefox is completely shut off... it shows the borders of the screen for 5 seconds, before showing the content (empty page) and then I can start and everything after that is fine.
In safe mode it opens without delay, so my question is, what in the normal start-up could be causing this delay, I have reinstalled firefox, disabled all extensions and plugins.Hello ellina, try disabling graphics hardware acceleration and check it again.
You might need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.).
Then perform these steps:
#Open Firefox ''Options'' window (''Preferences'' on Mac or Linux) as follows:
#* In Firefox 29.0 and above, click the menu button [[Image:New Fx Menu]] and select ''Options'' for Windows or ''Preferences'' on Mac or Linux.
#In the Firefox Options (or Preferences) window, click the ''Advanced'' tab, then select ''General''.
#In the settings list, you should find the ''Use hardware acceleration when available'' checkbox. Uncheck this checkbox.
#Now, restart Firefox and see if the problems persist.
Additionally, please check for updates for your graphics driver by following the steps mentioned in the following Knowledge base articles:
* [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]]
* [[Upgrade your graphics drivers to use hardware acceleration and WebGL]]
'''In safe mode, also, hardware acceleration is disable''', see : http://kb.mozillazine.org/Safe_mode
Thank you. -
I had Firefox v 16 or 17 on windows 7
A few weeks ago it told me to update, I did, and then it wouldn't load when I clicked on the icon
I used system recovery to get back to the prior version. I just ignored the "update firefox" messages for a while.
I decided to try to fix the problem and completely un-install firefox (all bookmarks, etc), re-install the newest version, and now again it won't load when I click on the icon.
(((And i have no system restore points that still have firefox)))
In the task manager firefox.exe *32 shows up for about 30 seconds after I click on the icon
I've un-installed, re-installed 10 times with no luck
I tried entering firefox in safemode (both by pressing F8 in system startup and also by holding shift down while I click on the desktop icon).
I've tried using chrome (which loads but freezes) and opera (which won't even install)
IE works
I have allowed firefox through the firewall, allowed all permissions for my user, and turned off my virus software entirely
I searched for the firefox profiles folder but did not locate it (It must have been deleted with my bookmarks, etc)
I scanned my computer using the microsoft security scanner suggested by mozilla, located 5 infected files, deleted those files, un-installed and re-installed firefox and still nothing
I have turned off everything in the task manager that appears to be non-essential. I've googled the things that have no description and found they are essential.
Am I doomed to a lifetime of IE?Certain Firefox problems can be solved by performing a '''''Clean reinstall'''''. This means you remove Firefox program files and then reinstall Firefox. Please follow these steps:
'''Note:''' You might want to print these steps or view them in another browser.
#Download the latest Desktop version of Firefox from http://www.mozilla.org and save the setup file to your computer.
#After the download finishes, close all Firefox windows (click Exit from the Firefox or File menu).
#Delete the Firefox installation folder, which is located in one of these locations, by default:
#*'''Windows:'''
#**C:\Program Files\Mozilla Firefox
#**C:\Program Files (x86)\Mozilla Firefox
#*'''Mac:''' Delete Firefox from the Applications folder.
#*'''Linux:''' If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it - see [[Installing Firefox on Linux]]. If you downloaded and installed the binary package from the [http://www.mozilla.org/firefox#desktop Firefox download page], simply remove the folder ''firefox'' in your home directory.
#Now, go ahead and reinstall Firefox:
##Double-click the downloaded installation file and go through the steps of the installation wizard.
##Once the wizard is finished, choose to directly open Firefox after clicking the Finish button.

Installed new battery, now computer is extremely slow
Hello,
My battery was DEAD, and I just installed the new one today. (It isn't the one from apple, but Read reviews that this was good so I got it). But I installed the new battery today, and every since, my computer gets really slow and starts to lag a ton after 5 mins of starting up. I've never had this problem before. I tried the smc reset (not sure if it is actually resetting). I did a pram reset as well. I also have a lot of space. It is even slow and laggy when I am not running any programs. Once I start a video, for example on skype, or on youtube, it lags like crazy.
Please help me fix this.
Thank you!Try having a technician install a battery made for your device.
Using things not made for your computer (or approved by the manufacturer) is a poor way to save money.

MacBook-won't install/update software unless in safe mode
Hi there, I am worried I have a virus. My computer won't update/install software unless in safe mode. It is also incredibly slow to use the internet and sometimes microsoft word will just close on me unexpectedly. It also gets very hot. I am unsure what to do about it. It is a white macbook with curved edges, I had had it about 5 years. Recently it has been having a lot of problems and I am unsure why.
This is not something you should blame on a virus... it's extremely unlikely that you have any kind of malware, and even more unlikely that that malware is a contributing cause of these problems.
I'd advise you to try the suggestions in my Mac Performance Guide. If nothing there helps, let us know what you found as a result of those suggestions. -
Cant get my MacBook Pro to let me log in because beta-Yosemite keeps restarting and I can't install new Yosemite- Tried safe mode but all I get is grey screen?
Have you tried booting in Yosemite's Recovery partition by holding down the command and R keys whilst booting?
You should be able to re-install OS X if you can get that far.

Why does my imac start up in safe mode
hi, imac starts up in safe mode. not every time, only when progress bar appears at startup.
I have had the Logic board replaced under warranty but it still started in safe mode.
sometimes when it has started the wifi symbol is missing and no wifi, other times the sound is not there and the symbol is missing on the top bar.
I then have to restart and it comes up good. sometimes the desktop top bar is not there until I press the mouse and then it appears.
don't know what to do, any Ideas anybody?How often does this happen? Do you have automatic updating enabled in Software Update? If so, then it's possible those were firmware updates being installed, not startup in safe mode. In a safe mode startup you are initially prompted for your password before proceeding past login.
If a firmware update was happening then the computer will restart on its own. If you interrupt the process then the update isn't installed, so it will try again on the next restart.
Safe mode is initiated by holding down the SHIFT key at restart. It should not occur without user intercession. -
Why does my MacBook Pro (13-inch, Early 2011) boot up UNBELIEVABLY slow in safe mode?
I've been using safe mode to delete glitchy software (non Apple certified) that I installed, but it just takes FOREVER to boot the computer.
Why is this the case?
Also, shouldn't the computer run a bit faster with only the "minimum" background applications running?
Thank you in advance for your thoughts.Booting in safe mode is slow because the startup volume is being checked and caches are being deleted. This is not something you should have to do many times in the life of the machine.

Is there any reason not to apply downloaded updates while in safe mode?
I'm thinking of doing it this time because logging in does a file system check and doesn't load my third-party items. Just trying to avoid update problems.
mini core duo Mac OS X (10.4.9)Installing updates while in Safe Mode is a very good idea. Although Apple does not make a specific recommendation to do so, they do recommend quitting all applications including any third-party software in order to minimize problems from incompatible software. Booting into Safe Mode goes the extra mile to prevent update problems.
In addition to installing in Safe Mode I highly recommend repairing the hard drive and permissions in advance as well. Also, clone your current installation to an external, bootable Firewire drive just in case you do have a problem. Much easier to restore a cloned backup than reinstall from scratch.
