Mini won't startup after Yosemite update - beeping

Hey All -
Just updated my Mac mini 2013 to OS X Yosemite. I left it alone for about an hour after it was finished downloading to complete the installation. When i came back, the mini was powered off and beeping a series of 3 beeps every 5 seconds. It won't power up. Was starting to get quite hot so i unplugged it.
Any suggestions??
Jason

The 3 beep error generally indicates a problem with RAM. (i.e. bad, unseated or incompatible)
If you have upgraded the RAM modules yourself:
1. Check to make sure that the modules are firmly seated in the slots.
2. Compare the spec's of the RAM with the "How to" link below.
3. Reinstall the original RAM modules that came in your Mini.
If you did not upgrade the RAM modules:
1. Check to make sure that the modules are firmly seated in the slots.
2. Seek help from your local Apple Authorized Service Provider.
For reference's:
see > Mac mini: How to remove or install memory
To find an AASP, go to > https://locate.apple.com/
Lastly there are no 2013 Mac Mini's. If you bought it new in the last year or so, then you most likely have a Mid 2012 model.

MAC Mini does not restart after Yosemite update

I bought my MAC mini in 2011 and I successfully updated to Mavericks with no problems. I am not sure why my MAC Mini will not restart after I updated to Yosemite. The completion bar gets stuck around 30%.
Any help or ideas appreciated
Larry

Okay, this is strange. I tried restarting three times yesterday with the same results. In fact I left it go overnight only to find the next morning that the bar was still stuck at 30%. I did a hard boot a little bit ago and waited a few seconds. I restarted an it booted up fine.

Mac Mini wont' Display Sleep after Yosemite Update

My Mac Mini is no longer going into Display Sleep. Instead I now see the Screen Saver. I have checked System Preferences | Energy Saver and it is definitely set to Display Sleep after 10 minutes (The default). What is interesting is that if I try to change the Display Sleep time (e.g. to 1 hour), when I go back into Energy Saver, it is back to 10 minutes - this doesn't look right! In fact none of the options (e.g. Wake on LAN) seem to stay changed.
This seemed to start after the update to Yosemite 10.10.1 a few days ago - but that might be coincidental. Until then Display Sleep had worked fine.
Any suggestions?
Thanks
Nick

Mac mini won't boot after latest update Maverick

My Mac mini running Maverick after an automatic update won't boot. " no bootable device -- insert boot disk and press any key"
What option do I have here?

Reinstall Mountain Lion or Mavericks
OS X Mavericks- Reinstall OS X
OS X Mountain Lion- Reinstall OS X
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is
three times faster than wireless.

Ipod mini won't connect after software update

I was using my ipod mini without problems on my mac powerboook until I downloaded and installed the latest ipod software updater yesterday. Since installing the application and clicking update in the software I can't get my computer to recognise the mini at all no matter what I do. Neither Itunes or the software updater sees my ipod and the ipod itself either says do not disconnect or shows a folder icon with an exclamation mark. Anybody know how to get out of this limbo state it seems to be in?

One thing you can try (AT YOUR OWN RISK - though I have done this on my own iPod mini using my PB and it has fixed issues similar to those that you are reporting), connect the iPod to your mac and then launch the disk utility app. If you're on a windows machine, this obviously won't help you although there may be a similar procedure. When the disk utility app comes up, if your iPod shows up in the left panel after a moment, highlight it by clicking on the name. If you try to verify it, you'll probably get a report of errors - don't panic - go to the erase pane and erase the drive (I think you can select either format with journaled or unjournaled - they both seem to work for me). MAKE SURE YOU"VE SELECTED THE iPOD DISK BEFORE YOU ERASE THE DRIVE!!!
After you erase the drive, you'll need to reapply the latest iPod update to restore the iPod OS (if you don't do this you may still be able to load music but it won't play and you'll still see the exclamation point display). After you reapply the update, you will hopefully back to normal. Re load your tunes and enjoy your iPod again!
Hope this helps.

Macbook air 2013 freezing at startup after yosemite update

My 2013 Mb air has started freezing at startup. performing a safe reboot seemed to help, but once I restarted immediately after rebooting it froze again. A second try apears to have done the trick, however, now my volume is completely off and non-responsive, and Safari is not really working. This is one day after updating to Yosemite.

same for my MBA 2013 model...its taking very long to show me the password box after clicking the username.....it happens everytime i restart...once it starts, everything is fine...if i had to force restart it (it froze couple of times), it takes really long to reboot...and again login is a big deal...any ideas/tips ???

Macbook Air won't start after Yosemite update

Hi all,
I have a late 2013 model macbook air (just out of the 1 year warranty). I updated to Yosemite last night and to complete the install I restarted the macbook when prompted, but it never turned back ok.
I can now hear the macbook trying to start up but it does nothing. I have tried to reset the SMC and I can see the power adapter change colour from orange to green for a few seconds but this does not appear to fix the issue.
Any help is appreciated,
Peter

If that doesn't work, this link may help you identify the problem
https://www.ifixit.com/Wiki/MacBook_Air_Troubleshooting#Section_MacBook_Air_won_ t_turn_on
If you still think its SMC issue you can try manual SMC Reset (At your own risk ). Steps are..
1. Open the lower case
2. Disconnect the battery connector and after few secords connect it back and close the lid

Motion 5 won't launch after yosemite update

After updating to yosemite on both my iMac and my Macbook pro, Motion will not launch on the iMac but it will on the pro. A window pops up after attempting to launch, saying: "You can’t use this version of the application “Motion” with this version of OS X. You have “Motion” 5.0.5."
Any ideas? Much Thanks.

You need to login to the App Store with the same Apple ID that you bought Motion 5 with for the update to show up.

Bootcamp won't load after Yosemite Update

So after trouble with Yosemite freezing in which i was able to fix, i tried to boot back into Windows on my bootcamp drive.
When i went into Startup Disk, i selected the Bootcamp Drive i had windows installed on. All i got was a black screen and then saw the message that the boot device could not be found. I restarted the computer and held down option to see the boot drives on that, but only drives that showed up was my OS X partition and Restore option. So my partition for windows was not found on boot.
I see a lot of people posting about losing their bootcamp partition or saying it was renamed, i don't know if this is the same issue. Is there any way to fix this or will i have to reinstall windows?

Here is the output for the following commands
Sudo gpt -vv -r show /dev/disk0
sudo fdisk /dev/disk0
diskutil list
diskutil cs list

SuperDrive won't burn after Yosemite update

Dear Support Community,
I have an Apple USB SuperDrive connected to my mid-2011 Mac Mini (2.5GHz dual-core i5) and recently updated to the Yosemite operating system. Following the update, I receive error messages whenever I try to burn a DVD (I have not tried to burn a CD recently).
I've done some quick searches and the closest thing I found was a suggestion to rename the com.apple.DVDPlayer.plist file. I have not tried that yet, but will likely do so shortly.
Might anyone else have had this problem and be willing to share their solution?
Thanks so much,

MBP slow startup after Yosemite update

Since I updated Yosemite to 10.10.3 on my MBP (late 2013, 2.3GHz i7, 16GB) it is much slower to startup (4 times longer) and the wi-fi is constantly dropping. Is there anything I can do?

Itunes won't display after Yosemite updated to 10.10.1. iTunes will play but no display.

My Mac just updated to 10.10.1. Now iTunes won't display on screen. I can play songs by hitting the play key. If as I am typing this I click on the iTunes icon the tool bar does not show up at top for iTunes, but the tool bar will show up if I shut down safari. How do I get my iTunes app back?

OPPS!! Figured it out still had second monitor cord in, and thus was it displaying on the monitor that wasn't on. Duh
