When I put my iMac to sleep it puts my Mac Mini to sleep as well.

The Mac Mini goes to sleep when the iMac is put to sleep and the Mini will not wake up unless the iMac is awake. I have made sure that all sharing is off but it did not fix it. Cannot figure it out!

... does my iMac model... support Hibernatemode 3 alias "Safe Sleep" to protect my Mac against damages due to power outage?
You can set hibernate mode to 3, but it seems to me its only benefit could be if power were to be lost after the iMac was already sleeping. Sleepimage is written to disk prior to system sleep. If your iMac lost power while it was "awake" you would certainly lose any unsaved work no matter what hibernate mode you choose.
The problem is that an iMac without power no longer sleeps, it's dead. Upon restoring power you need to cold boot, and I seriously doubt sleepimage can be forced to load in that event. Sleepimage is loaded upon wake from "safe sleep", not from boot as far as I know.
It is simple enough for you to try, so go ahead and see if it does what you want. Other than creating a 16 GB sleepimage file it did not appear to do anything beneficial on the iMac I am using though (a later model).
The file location is /private/var/vm/sleepimage
Configure hibernatemode, verify the file is created, do some work on your Mac, don't save it to disk (and don't use Pages or similar app that saves work on its own), let it sleep, then pull the plug. I think you will see what I mean.

When i put my Mac for sleep it takes more time than normal ( 20 secs). Sometimes, coming back from sleep the system is not responding (freeze).

When I wake my iMac from sleep, the wireless does not connect. I have to shut shutdown and then restart and then it connects. I am running Lion 10.7.3 Any thoughts?

Been waiting along time for this problem to be fixed. Unfortunately the update hasn't help at all and even made the situation worse. Now my airplay connection from iMac to stereo abruptly stops after about 10-15 min. so I have to go over and quit wifi, start it up and find my airport network. Not sure why it always has a problem with the apple airport network. My neighbor's pc network is always there.

Everytime I put my Mac Mini to Sleep, Finder becomes completely unresponsive. How do i fix this?

Hi,
Everytime I put my Mac Mini to Sleep, Finder becomes completely unresponsive. I've tried several Terminal commands to kill/quit/relaunch it, but nothing seems to work. Once my Mac has been put to sleep there is nothing I can do to get it back after I have woken it up. I always have to restart my computer, and even then, I have to hold the power button to shut it down because it will never fully shut down from the restart. I have a feeling that Finder is still running in the background and not allowing the mac to shut down. I'd rather not have to reinstall my OS. Does anyone have any idea what may be causing this problem?
Thanks,
Andrew

Hi Andrew, what all is connected USB wise?
One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for Sleep/Wake problem in Safe Mode...
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
Reboot, test again.
If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or some USB or Firewire device, or 3rd party add-on, Check System Preferences>Accounts>Login Items window to see if it or something relevant is listed.
Check the System Preferences>Other Row, for 3rd party Pref Panes.
Also look in these if they exist, some are invisible...

How do I enable TDM?
Make sure both computers are turned on and awake.
Connect a male-to-male Mini DisplayPort or ThunderBolt cable to each computer.
Press Command-F2 on the keyboard of the iMac being used as a display to enable TDM.
Note: In Keyboard System Preferences, if the checkbox is enabled for "Use all F1, F2, etc. keys as standard functions keys," the key combination changes to Command-Fn-F2.
How do I exit TDM?
To leave TDM, press Command-F2 on the keyboard of the iMac that is in TDM. You can also exit TDM if you shutdown or sleep either computer or detach the cable.
Can I use a third-party keyboard or older Apple keyboard to enable TDM?
Some older Apple keyboards and keyboards not made by Apple may not allow Command-F2 to toggle display modes. You should use an aluminum wired or wireless Apple keyboard to toggle TDM on and

I have a late 2012 iMac and a late 2009 mac mini. I want to know if I can take the 8 GB of ram from the iMac and install it in my mac mini.

I have a late 2012 iMac and a late 2009 mac mini. I want to know if I can take the 8 GB of ram from the iMac and install it in my mac mini.
According to Cruicial my mac mini could use:
Module Size: 8GB Kit (4GBx2)
Package: 204-pin SODIMM
Feature: DDR3 PC3-8500
Specs: DDR3 PC3-8500 • CL=7 • Unbuffered • NON-ECC • DDR3-1066 • 1.35V • 512Meg x 64
Also According to Cruical my iMac uses:
Module Size: 8GB Kit (4GBx2)
Package: 204-pin SODIMM
Feature: DDR3 PC3-12800
Specs: DDR3 PC3-12800 • CL=11 • Unbuffered • NON-ECC • DDR3-1600 • 1.35V
I want to increase the ram in both computers.
So, can I put the iMac ram in my mac mini and then I'd only have to buy ram for my iMac? Naturally the ulitmate test will be when I actually install it, but having an expectation of success or failure will allow me to plan on what to spend money on.
Thanks,
Bear

Thanks for the responses. I probably wont even try as my priority is Ram for the mac mini. 2 is not enough. 8 for my imac is okay for now.
Somewhere I thought I'd heard that faster Ram would simply clock at the lower speed. It seems that I am incorrect.
Thanks,
Bear

Hi there,
The simplest way is to drag it across wirelessly using the 'Airdrop' application once both computers are near one another. 'Airdrop' can be found near the top, on the left hand side menu, within 'Finder'.

Is it possible to use an iMac as the display for a Mac mini?

Is it possible to use an iMac as the display for a Mac mini?

iMacs late 2009 or newer can be used in Target display
mode. Any older, no can do.
The only other way is via network Screen Sharing or
some otherVPN network like solution. The issue here
though is that video performance will be pretty severely
hampered.

Screen freezes up when I wake the iMac from sleep

Hi, all. This is my first post to Apple Discussions, so please pardon me if this is a dumb question. I have had a problem twice in the last 24 hours. I have an iMac G5 that I keep on most of the time. I do put it on sleep mode when I'm not using it. This morning, and then again this evening, I had the iMac on sleep mode. When I woke the computer, the screen came up, as usual, but when I went to click on the Safari icon, the screen became fuzzy and locked up. Powering the unit down was the only way to restart the computer. After that, things worked fine. However, this is a new occurrence. Is it something serious? Is it easily fixable? Is this common with iMacs? Just wondering. In the meantime, I'll probably just use the "shut down" command when the computer is not in use. Thanks for any advice that you can offer.

Been waiting along time for this problem to be fixed. Unfortunately the update hasn't help at all and even made the situation worse. Now my airplay connection from iMac to stereo abruptly stops after about 10-15 min. so I have to go over and quit wifi, start it up and find my airport network. Not sure why it always has a problem with the apple airport network. My neighbor's pc network is always there.

I just purchased a new airport extreme 802.11ac I set it up and runs fine when i put my mac to sleep i come back and it can not find my airport i have to restart

I PURCHASED THE NEW AIRPORT EXTREME 802.11AC I SET IT UP AFTER I PUT MY MAC TO SLEEP I COME BACK AND IT SAYS CAN NOT FIND AIRPORT EXTREME I HAVE TO RESTART AND IT FINDS IT.

Try the following, in order, until (hopefully) resolved:
1a. Delete Preferred Network(s)
System Preferences > Network > Wi-Fi > Advanced > Wi-Fi tab
Under "Preferred Networks," delete the network(s) you regularly use from the list.
1b. Delete AirPort Keychain Entries
Launch the "Keychain Access" application located in Applications/Utilties.
In the windows on the left side: Select login for Keychains and "All Items" for Category.
Click on the "Kind" filter at the top, and look for any "AirPort network password" entries...and delete them.
1c. Add Preferred Network(s)
System Preferences > Network > Wi-Fi > Advanced > Wi-Fi tab
Add the preferred network(s) using the "+" button.
Restart or log out then back in.
2. Move System Configuration Files
(Note: You will have to reestablish your network connections settings.)
Go to /Library/Preferences
Move the SystemConfiguration folder to the desktop.
Restart your Mac. (Note: OS X will rebuild the files that are now sitting on your desktop. If this doesn't resolve the issue, you can move the folder back to it's original location.)

Turning off my HDTV puts my mac mini to sleep and turns off Eye TV

I have a mac mini dual core connected to my Panasonic 26" Viera HDTV via a DVI/HDMI cable. I am using it (amongst other things) as a personal video recorder with the Eye TV 410.
However I find when I turn off the TV it also puts the mini to sleep (even though my energy saver settings say it should never go to sleep). The result of this is that when I finally do get the machine to reawaken by pressing the power button at the back (I have bluetooth mouse and keyboard and the computer doesn't respond when I wiggle these) Eye TV has quit and the programs I had set up to record haven't recorded.
I've not been able to find someone with a similar problem and I'm wondering what I can do. I've previously been using my PowerBook with the TV and the Eye TV and this problem did not occur. I am using Eye TV 2 software.
Any help greatly appreciated.
Mac mini dual core Mac OS X (10.4.6) Also own PowerBook G4 1.5Ghz

Hi there,
I had exactly the same problem as you, so you are not alone. I wrote an email to elgato and they were rather unhelpful! "Quit elgato before turning your tv off or just don't turn off your tv"! Thanks for those gems of advice!
I wish I could help you with what I did to get it working as it is now. The only thing I can think it is is that I changed my connection from DVI-HDMI to DVI-VGA. This means that elgato is no longer crashing when I turn my tv off.
Sorry, I know that is not very helpful but that is how it worked for me. Hope you manage to sort it out.

imac G5 Mac OS X (10.4.5) white ipod nano

When I open my iMac, I get this message - Your Mac OS X startup disk has no more space available for application memory. ???????

When I open my iMac, I get the following message : Your Mac OS X startup disk has no more space available for application memory. Then it says to quit applications not in usw and to close windows and remove files from startup disk. It lists Safari, email and Finder. I force a quit on all applications yet the same message comes up every time I open an application. What do I do to get rid of this once and for all? The computer is not even two years old and is only used for email and Safari. Help will be greatly appreciated,

The message has nothing to do with low disk space.
There is excessive swapping of data between physical memory (that is, the memory chips on the logic board) and virtual memory (one or more files on the startup volume.) That activity is relatively slow and causes the whole system to be less responsive. It can happen for two reasons:
A long-running process with a memory leak (a kind of bug)
Not enough memory for your usage pattern
Tracking down a memory leak can be difficult, and it may come down to a process of elimination.
These instructions are for OS X 10.9 ("Mavericks.") The procedure may be slightly different for earlier versions of OS X.
When you notice the swap activity, open the Activity Monitor application and select All Processes from the View menu, if it's not already selected. Select the Memory tab. Click the heading of the Real Mem column in the process table twice to sort the table with the highest value at the top. If you don't see that column, select
View ▹ Columns ▹ Real Memory
from the menu bar.
If one process (excluding "kernel_task") is using much more memory than all the others, that could be an indication of a leak. A better indication would be a process that continually grabs more and more real memory over time without ever releasing it. Here is an example of how it's done.
The processes named "Safari Web Content" render web pages for Safari. They use a lot of memory and may leak if certain Safari extensions or third-party web plugins are installed. Consider them prime suspects.
Another process often implicated in memory leaks is "inkjet4" or "inkjet8," which is a component of the HP printing software. If it's present, force-quit the process in Activity Monitor to solve the problem temporarily. Empty the print queues in the Printers & Scanners preference pane (which has a slightly different name in each recent version of OS X.) If you don't use an HP printer, remove the software. Otherwise, if the problem is recurrent, update the software (which may not help) or contact HP support.
"Wired" memory should be a small part of the total. That memory is not swapped, but it makes less physical memory available which may then result in swapping. If you have a lot of wired memory, that's usually an indication of a memory leak in a third-party program that modifies the operating system at a low level. Ask for guidance in that case.
If you don't have an obvious memory leak, your options are to install more memory (if possible) or to run fewer programs simultaneously.
The next suggestion is only for users familiar with the shell. For a more precise, but potentially misleading, test, run the following command:
sudo leaks -nocontext -nostacks process | grep total
where process is the name of a process you suspect of leaking memory. Almost every process will leak some memory; the question is how much, and especially how much the leak increases with time. I can’t be more specific. See the leaks(1) man page and the Apple developer documentation for details.

Fire wire incompatibility between OS 10.10 (IMAC) and OS 10.4.11 (Mac Mini)

Fire Wire does not work between my Imac running Yosemite, and my Mac Mini running 10.4.11. It does not seem to be a hardware problem. I was wondering if anybody knows why? Is there something between the two OSs that makes fire wire a no go? Is it a Power PC vs Intel issue. Are there any work arounds? Both computers drop into target mode correctly, but neither will put an Icon up on the other's desktop. Speculation is that I'd have to run 10.6+ to get fire wire to work with Yosemite.
Sure would be nice to know...

Is it a Power PC vs Intel issue.
I believe that is the problem. Here are several articles from Apple:
