Ever since upgrading to 10.8.4, iMac has problems after waking up from sleep

Finder windows are blank and non responsive, with spinning beachball...try to restart Finder, endless beachball...I didn't have this problem at all with 10.8.3...Help!!

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, or by a peripheral device.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including Wi-Fi on certain iMacs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

IMac OSX Lion 10.7.4 loses Wifi after waking up from sleep

So basically just like my title states, when my computer wakes up from sleep about 70% of the time the internet will not work. My mac does see and connect to my network, but something isn't being sent as I have no connection when trying to surf the web. I then reset my modem and router, and it still doesn't work. What fixes my problem is a reboot or Logging out and back in. I don't know why that does the trick but it does. I have looked at http://support.apple.com/kb/DL1501, however this update is only for 10.7.3. Is there something I can do to fix this problem?
As a side note, if I have Parallels Desktop running my iMac's wifi after sleep will not work, but it will work in the Windows 7 parallel. Why is this?

27" imac will not turn disply on after waking up from sleeping

I have 27" imac with 2nd monitor attached. when in sleep mode the 2nd monitor will wake up but the imac itself will not turn the screen on. (what is funny is that i can log in but the only monitor i can actually see is my 2nd one.) i must play with the power button several times to either get the imac to reboot or to wake up. any fix out there?

I have had this same problem with my mid 27inch mac 2011. I recently yesterday took it to the genuis bar so they could try to give me a solution. I showed the technicians many threads with my same problem and they acted as if I was crazy and the issue was absurd/ non valid. This problem only started happening when I upgraded to lion. I suppose to get the coputer back in a couple of days. The onl god thing I had going was all the kernal panics that were listed because of the machine having to be restarted everytime. I will provide any informatio they give me.

Ever since upgrading to Lion my iMac opens to a different admin than the one last used and has to be switched. How can that be changed?

How can I change which user boots at start up? Ever since upgrading to Lion X my iMac no longer opens to the user on it prior to shut down. It now opens to a user who is virtually never on - which is actually me under a different name. This division of my Mac happened when I switched to my new Mac and didn't know I had to use the same name to transfer my data. My old data is listed as a separate user. Over time my old user name brings up a window full of ???? at the bottom. It looks like no apps ever upgrade there. It is driving me crazy to have to now switch back each time I start my computer. (I am using an iMac with 3.06 GHz Intel Core 2 Duo processor).

Ever since upgrading to Lion I keep getting the error message "disk was not ejected properly."

Ever since upgrading to Lion on my iMac G5 Intel Core 2 Duo, I keep getting the error message "disk was not ejected properly." I have repaired permissions and reformatted my external LaCie 2TB USB hard disk, but the error continues. I use this disk for my Time Machine backups. This always seems to happen when the computer wakes from sleep, but not consistently. The computer was asleep overnight and backed up as soon as it awakend this morning. Two hours later I get the improper ejection message. I have used the same external disk with Snow Leopard (all versions), but never had this error message or problem. This disk has been in use without any problems since February, 2011. Upgrading to Lion is when this problem began. This is the below message (but from online image from Snow Leopard, but Lion message is essentially the same).

I had a similar issue. Mine was with a Seagate GoFlex drive. The solution was to install GoFlex for Mac 1.1.2 which included a 64-bit driver to disable the drives built in sleep timer:

Freezing during use ever since upgrade to Lion

My Macbook doesn't freeze on login. It doesn't freeze after waking up from sleep.
It works fine and then after a bit of use - it freezes.
I can detect no consistent pattern to the freezes.
I have gone to NEVER having to reboot (or whatever the mac equivalent is) to having to reboot about 6 times a day. It is like I am back on a PC
I have the same amount of apps open that I did when I was on Snow Leopard and it never froze.
Did I say Never? I meant never, ever, ever to infinity, never froze.
Now it freezes quite often. Love my MAC!!! Not loving the freezes ever since the Lion upgrade.
Apparently freezing is happening quite a bit to other upgraded Macs. Don't know what the deal is but PLEASE FIX THIS APPLE!!!!

Please be more specific.   "Freeze" means different things to different people.
Please compare your experience to mine, observed in 10.7.x on a quad-core iMac:   I'm doing "ordinary" stuff and all of a sudden the entire display --actually the main display and on an attached monitor-- freezes... stays exactly as it was some instant before. The mouse pointer cannot be moved by any means, including plugging in a new mouse. There's nothing to do but shut down and reboot. Reboot always succeeds, everything is normal -- until the next time. Which is usually several weeks away, but in one case, the next day.
Under the technical hood, the system is unresponsive on the LAN, doesn't even respond to a ping. And afterwards, I've found no trace of these incidents in the Console log --as would occur with ordinary kernel panic and many other failures, I guess. These are all situations in which the Mac system realizes it can't continue and tries to sign-off as gracefully as possible, more-or-less "softly" crashing.   Note: as far as I can recall this iMac has kernel-panicked exactly once since I bought it.
I've started keeping a log of these hard crashes. The last two occurred while I was browsing in Firefix.   If this pattern repeats, I'll definitely want to look into that. But for technical reasons it seems very, very unlikely that an application program can hard-crash a Mac.
Other than a Firefox problem my mostly superstitious suspicion is that I should have bought the highest-price RAM upgrade rather than the medium-priced set I added after installing 10.7 <grin> Memory failure would explain the problem, I think.

IMac hangs waking up from sleep mode, what can I do?

I have an iMac - early 2008, Inter Core 2 Duo, screenshots of full specs attached below.
I upgraded to Mountain Lion about 3 weeks ago. No problem until 2-3 days ago when the iMac started to 'hang' after waking up from sleep mode.
I'd try to launch Safari but the icon just bounces on the dock.
Force quitting all open apps, force quitting Finder. Still nothing.
Can't shut down unless I hold the power button down.
Then on restart it says something about an application that was previously unresponsive...try to reopen it or wait 50 seconds (or thereabouts) - I choose the latter option.
I've tried to do the usual verify/repair permissions and verify/repair disk. No problem found.
Incidentally, this has only been happening since 'upgrading' to iTunes 11. Coincidence?
Can someone help?

Ok, I've done everything suggested above except for running the Disk Utility from the recovery partition, as I will have more time to spend on it tomorrow and that's something I'm too scared to try in a rush....!
I've made a screenshot of the energy saving settings changed to your suggestion, could you let me know if that's what you meant?
I really appreciate your help by the way

Ever since upgrading to iTunes 11.0, I can no longer sync Contacts and Calendar from my iMac (10.7.5) To my iPad2 (6.0.1) via Wi-Fi. I believe All my settings are correct. Device is recognized and sync From iPad is possible.

Thank you Meta, but I could not get the calendar and contact sync with Gmail to work. Apple support already suggested to use Google or a Windows PC. Maybe I should actually reset and try my old Windows PC. Seriously, ... can this be the solution after a Mac OS update for pure Apple users?

Ever since upgrading to Mountain Lion, my AOL messages sometimes, but not always open with a blank page. If I open AOL in Firefox, the messages open fine. This does not happen with any messages by any means, and it is not any type of certain message. In fact, in the same screen I can often open an email from the same sender with email intact. This is weird. Sometimes I close the page and open a new page. Sometimes that works and sometimes it does not. It is a very annoying thing.

Hi,
When you start Messages fro the first time you are asked for an Apple ID
When this is verified and entered it appears in Messages Menu > Preference > Accounts and is Enabled.
The App should have also picked on on those iChat Accounst you had before.
These should be Enabled if they were when you last used iChat.
Exactly which "Accounts" are logged in can be seen in Message Menu > Accounts and will include the iMessage "Account" and Bonjour.
In the Window menu you will see CMD +0 for the Messages window and CMD+1 for the "Buddies" window which is a combined list at this stage.
Go to the Preferences > General Section and Untick the "Collect all accounts into one list".
This will give you separate iChat type Buddy lists.
You can check if that account/Buddy list is set to Invisible or if in the Preferences > Accounts > Security you have settings that will block some people from seeing you as On line.
You are saying Buddies can see you as On Line which implies they are still sending to your AIM based Names (@Mac.com is a valid AIM Screen Name)
I am not sure from your post if you are trying to iMessage their email IDs thinking they are Apple IDs and that they are using Messages as well.
There is no Buddy list for iMessages side
No-one can tell you are "On Line" until they have your details in the "To" spot in Messages with the correct iMessaged contact info (iPhone Number or Apple ID)
Obviously an Apple ID can be an email or look like one.
In some cases they are also valid AIM Screen Names as well.
In the case or the @mac.com name you may have linked this Apple ID to iMessages as well.

Have been using Lightroom on my Apple computer for years. Now, ever since upgrading to Apple's Yosemite operating system I get an error message (150:30) every time I try to open a lightroom file. Has anyone else experienced this problem? Also how do I subscribe to Adobe's Premium Support? Every time I've tried (through contact support) I just get taken on an unending loop.

I think we need a lot more information.
Exactly what does the message say?
Exactly what files are you trying to open?
Exactly how are you trying to open them (what menu command or button or mouse action or keyboard shortcut)?
And lastly, what version of Lightroom are you using?

There are two possibilities, 1)it is a software problem which will be fixed.
2)It is a hardware problem, and youll have to take it to an iStore.
BUT there is something you should know.
If your under apple care, its free.
If you are not under apple care, itll cost you something to find out where the problem is (i dont live in the US so I dont know) and then extra cost for the reapair itself.

How to Perform an Archive and Install
An Archive and Install will NOT erase your hard drive, but you must have sufficient free space for a second OS X installation which could be from 3-9 GBs depending upon the version of OS X and selected installation options. The free space requirement is over and above normal free space requirements which should be at least 6-10 GBs. Read all the linked references carefully before proceeding.
1. Be sure to use Disk Utility first to repair the disk before performing the Archive and Install.
Repairing the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported, then quit DU and return to the installer.
2. Do not proceed with an Archive and Install if DU reports errors it cannot fix. In that case use Disk Warrior and/or TechTool Pro to repair the hard drive. If neither can repair the drive, then you will have to erase the drive and reinstall from scratch.
3. Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When you reach the screen to select a destination drive click once on the destination drive then click on the Option button. Select the Archive and Install option. You have an option to preserve users and network preferences. Only select this option if you are sure you have no corrupted files in your user accounts. Otherwise leave this option unchecked. Click on the OK button and continue with the OS X Installation.
4. Upon completion of the Archive and Install you will have a Previous System Folder in the root directory. You should retain the PSF until you are sure you do not need to manually transfer any items from the PSF to your newly installed system.
5. After moving any items you want to keep from the PSF you should delete it. You can back it up if you prefer, but you must delete it from the hard drive.
6. You can now download a Combo Updater directly from Apple's download site to update your new system to the desired version as well as install any security or other updates. You can also do this using Software Update.
