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 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 Won't Sleep after installing 10.4.6

My Mac Mini wakes itself up after just 1 minute of putting it to sleep mode. I've tried restarting my mini, and tried quitting all apps and disabling airport and bluetooth- but it still won't sleep! Anyone else experiencing this problem, I didn't have this problem with 10.4.5 and I've installed no other software since then...

This is for a Mac that won't sleep.
First, read things in Apple doc.#25801 on sleep settings.
USB devices and hubs often cause Macs to not sleep or wake quickly from sleep (notably HP printers and scanners, HP all in ones, and Cannon scanners). Disconnect all USB except for keyboard and mouse and try. If it sleeps, add one back at a time testing after each one to find the culprit.
If you've set your Mac to recieve faxes, it may not be able to sleep. It might also have a damaged preferences file.
If you use your Mac for faxing, open System Preferences. click Print & Fax, click the Faxing tab, and uncheck the Recieve Faxes On This Computer box.
If that does'nt work or you've never faxed on your Mac, go to Finder/Hard Drive /Library/Preferences/SystemConfiguration and delete the com.apple.PowerManagement.plist and com..apple.AutoWake.plist files (if your Mac asks, type your admin. password).
If the latter file isn't present in the folder, go to user name(probably your name)/Library/Preferences, delete the com.apple.systemuiserver.plist file, and reboot your Mac.
Hope this helps!
P.S. One member here reported this (Michael Gleason);
"I have had this problem with my IMac G5. It is surprisingly irritating. LaCie's Silverkeeper backup software was the cause. By default it gave itself permission to wake up the computer to check if a backup was needed. Do you have this or a similar program installed which has scheduled activities including wake-up permissions as an option?"
Dave Hamilton provided this link, xlr8yourmac.com, to a member, which addresses failure of deep sleep with some users that updated and added new FireWire and USB cards.
tomhorvat adds this; After few days of messing around I found out that I had desktop background (wallpaper) set to change every 1 minute.
After unchecking "Change picture..." in system preferences (under Desktop/Screen saver), my powerbook went to sleep all by itself.
Cheers!

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 will not boot after Security Update 2008-007

Hello,
A G4 Mac Mini machine I was asked to take a look at will not boot after the owner (succesfully) installed Security Update 2008-007 from Software Update. Booting always hangs at the blue screen after the Apple logo, and booting in verbose mode reveals that WindowServer is crashing repeatedly. Permissions and filesystems have been repaired, PRAM reset, etc. Safe boot also exhibits the same problem, but it is possible to boot to single user mode. Hardware checks out fine with diagnostic utilities.
Any suggestions on how to fix this? Unfortunately, backups are not available (it's not my machine =).

Hi Arkku , and a warm welcome to the forums!
I'd certainly give Sig's advice a try first.
If that should fail...

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.

Any ideas how to solve?

You can go into the OS X Server Forum and search for this issue. I think there are some discussiom threads that discuss it and you can read some of the solutions.
I'm also running Mountain Lion 10.8.2 and OS X Server on a Mac Mini and it won't sleep if I have the File Sharing, VPN and Printer Sharing services running. To me, this is a good thing as a server is usually available to client machines 24x7.
I did experiment and turned off each service one at a time to see which ones deny the sleep function and I found all 3 do.
Here's an example from my server. The bold entries are the culprits for my server.

Mac Mini will not load after recent update.

My late 2012 model Mac Mini just had a software update and upon rebooting, my login name did not populate. I rebooted again and now I get the gray screen with spinner and progress bar. Once the progress bar loads I have just the spinner for a minute or so before it cuts off completely. I use a wireless MAC keyboard and it will not load into safe mode when I try holding down SHIFT upon reboot. Any suggestions?

Try Safe Mode with a wired KB
Use a PC KB if necessary

and try repairing the startup disk
Next reinstall the OS

Mac book pro won't wake from sleep after Yosemite update

Since updating my laptop to Yosemite my MacBook hasnt woken from sleep
i can hear it turn on but the screen and keyboard don't light up
mac book is only 3 years old retina display

Mike Doolin wrote:
I think I may have found the fix for this. My MacBook Pro was dying in its sleep every time (after installing Snow Leopard), whether it went to sleep automatically or I used a Hot Corner. I went into System Preferences>Desktop & Screen Saver and changed the screen saver to Flurry, and it works now. I had had it set to a folder containing a single .pct file that I had created.
Good advice Mike! When in doubt check the ScreenSaver settings.
Definitely seems that it has a problem with that pic... In my case, selecting any images instead of the default setting (no screensaver) seems to have cured my non waking issue on my early Macbook Pro in Snow Leopard.
My original problem was that no amount of trackpad input woke it, but the space bar did. The space bar seemed to wake it up with the previous Screen Saver setting. Now trackpad wakes it up (even from total sleep as well as screen saver), too. Might be nice to know about if this is an intended 'feature' as a security trick. Otherwise I consider this a bug.
My vote is that it's a bug.

Wifi wont turn ON after Yosemite update

After hours of trying to update from Mavericks, i finally got into OS X Yosemite; but i cant turn the Wifi ON.
How can i solve this issue?
Anyone having the same problem?
Thanks.

redondofuentes wrote:
Thanks for the try Eric... but none of these work. My wifi is stuck in the off position. When I click the "turn wifi on" buttoning my network setting or from the network menu bar... nothing happens.
None of these articles address this issue.
I tried the disabling of AirDrop in Terminal too and my system said it could not find the filE
This is the only thing that worked for me.
1. Go to System Preferences and open 'Network' - or click your wifi triangle along the top tool bar and select 'open network preferences'.
2. Click your wifi on the left hand side from the list, and then click the small cog at the bottom of that box, and click 'Make Service Inactive'.
3. Once you've done that, click the minus to delete your wifi as an option from this box.
4. APPLY!!
All other instructions I read said to click the plus and add your wifi again and then restart. Well that did nothing for me, infact it did nothing about 7 or 8 times, soooooo...
5. Restart your computer now, without any wifi configuration setup.
6. Once restarted, go back into system preferences, into network, and use the + button to add a wifi connection back into your computer. With any luck, you will be able to click on 'Turn wifi on' and it will actually work!

Mac mini A1176 doesnt start after Security update 2012-001 (10.6.8)

it has istalled 2Gb RAM insted of original 500Mb but it used to work well before the update

Also:
Apparently some are reporting that this causes the older PowerPC (PPC) applications that are supported in 10.6 via 'Rosetta' to crash upon attempting to open/save/print using any dialog box, or fail in other similar ways such as simply not printing or quitting, or freezing/hanging/crashing of the application.
You might wish to read:
http://www.macintouch.com/readerreports/snowleopard/index.html#d02feb2012
If you are unsure if you are still using PowerPC apps, if the application is currently running, look under the 'Activity Monitior' (in Applications -> Utilities), or alternatively you could check in the System Profiler, Applications. Check the column "Type".
Here is a fairly simple way you can restore you system and restore you applications functionality again, if you don't have a recent clone or good Time Machine backup that you can restore from. If you do, restore from your backup prior to having installed the Security Update 2012-001.
Time Machine restore: http://support.apple.com/kb/ht1427
If you are restoring a backup made by a Mac to the same Mac
With your backup drive connected, start up your Mac from the Lion recovery partition (Command-R at startup) or Mac OS X v10.6 installation disc. Then use the "Restore From Time Machine Backup" utility. Select the backup prior to your issues, and it will be restored back to the state it was in at that time.

Mac Mini i7 After Yosemite update, sleep mode affecting internet connection

Hi,
I got a Mac Mini i7 for July 2014 everything was awesome. On Monday, October 27th 2014, I notice the port where my Mac Mini is connected, the light is amber colour. When this happens there's no internet connection for the Mac Mini and affects the router has it slows the connection. After doing the following:
1. Turn off Modem for 20mins (hard reset)
2. Turn off Router for 20mins (hard reset)-Router Netgear WNDR4000
3. Set Service Order
4. Change Ethernet Cable
5. Renew the DHCP
I found out the when the Mac Mini goes to sleep mode thats when connections drops. I test where i set it to 1min and voila the port is now amber colour.
I don't want to keep the Mac Mini i7 in "never" status has it decrease life.
Put hard disk to sleep when possible and Wake for network access are checked.
Of course before the update, everything was working fine. Any ideas is appreciated.
Thanks,
Retsel Adrec

Re-installing Yosemite fixed this problem.
Thanks.

Mac mail CRASHING after Yosemite update 10.10.3

Are you KIDDING APPLE?
mac mail CRASHING after Yosemite update 10.10.3
The program is completely unusable and crashed after update.
Computer is less than 1 month old and can't run a basic mail program
I REALLY HOPE APPLE FIXES THIS BUG ASAP
Without fix I will return the computer

True,
I also have AppleCare, but unfortunately, after calling them they can't determine what is creating the problem either.
Other forums have shown other troubleshooting steps which didn't solve my problem, but may help others:
Mail app keeps crashing after Yosemite update
Mail crashing after upgrading to 10.10.3
Lets cross our fingers that 10.10.4 will be out shortly to fix this

MAC Mini late 2014 Sleep Wake issue

I just bought a MAC Mini late 2014 version with Yosemite pre-installed, and got a similar sleep wake problem.
It's connected to an ASUS IPS 27" screen using HDMI interface. When the Mac goes to sleep after 15 min, or when I press the button to force it to sleep.
If you type on the keyboard and the trackpad within 1 minute (before the screen also goes to sleep because of no HDMI signal), then the wake up will work.
If you wait till the screen goes to sleep also, then no matter how hard you pound on the keyboard or on the track pad, the MAC will not wake up.
The only way to wake it up is to power off the screen, then power it on again. Then type on the keyboard or move your track pad while doing that.
This is really annoying. I have to set to "Never" turn the display off to avoid this issue.
Called the Apple tech support who recommended I set up the energy saver like this below. But still could not fix the issue.
He told me to bring the Mac mini back to the shop to check.
I doubt it's a hardware issue. My theory is that this could be a software bug that somehow
the setting of "Prevent computer from sleeping automatically when the display is off" is not in effect even if you turned it on in the power saver preference.
So, when the computer goes to sleep, there is no more HDMI signal, then the screen also goes to sleep.
And if "Prevent computer from sleeping automatically when the display is off" is not in effect, then even if you type on the keyboard, the computer will not wake up as the screen is asleep. The screen will not wake up as no HDMI signal comes from the computer.
This turns into a viscious cycle, or a deadlock. Nobody is waking up.
This is simple logic. I don't know why systems are designed to work like that. Just too annoying....
I hope apple can fix this software bug asap.
I did try to convert my HDMI cable to min-display port and try to plug that into the thunderbolt port to see if it helps.
The same issue appears. The only difference is, with the HDMI port, once I am able to wake up the computer by power cycling my screen, i will see that I am prompted with a login screen, even if I set up my computer to auto login.
but when I use the display port, when I managed to wake up the MAC, it bypasses the login screen.

Some updates on this. I tried two other 22" screen. Both of the seems to be working fine with sleep wake, but takes between 40 sec to one min to wake up after you typed something.
Topcon hdmi 22" screen
17 sec after keystrokes to turn wake screen
40 sec to wake computer
AOC hdmi 22" screen
19 sec after keystrokes to turn wake screen
38 sec to wake computer
I tried to switch to two other HDMI cables to see if it'll improve the situation of my original ASUS VX279 IPS HDMI screen.
But it didn't. Still never wakes up after it the MAC goes to sleep until you power cycle the screen.
I guess there is some hardware compatibility issue here.
Let me bring my mac mini to the shop to see if a replacement will help.
