IMac :: System Slow After Screensaver Or Sleep
Dec 19, 2009
My new i5 iMac has been really slow after I get out of its screensaver or take it out of sleep. Even if its on the screensaver for a minute, moving the mouse causes it to freeze and try to load the desktop. This takes about a minute before my computer is fully functional again. Also, I don't know if this is just me thinking this or if its actually a problem, but the computer seems a lot slower than my previous, a 24" 3.06Ghz iMac.
Another thing, the fans seem to spin a lot more with this computer. Watching a YouTube or Hulu video makes the fans spin a ton. I've never had that happen with a Mac before. The computer also gets literally too hot to touch. Anybody else have this?
Also, on a (kind of) unrelated note, Windows performance with this is horrible. I've tried Windows 7 and Vista, and both run... adequately. The fans also spin a ton in Vista (what I currently have installed due to there being no 27" drivers for 7 yet).

When my IMac goes to sleep, the screen saver is "frozen". The only way to get to my login accounts is by "cleaning" the screen with my mouse. It's as though the screen is not refreshing itself after going to sleep and whatever the last image was, it stays. However, it's not locked up or anything. I just need to move my mouse around over the login accounts and it slowly clears away the screen saver so I can see where to click to log in. I've tried disabling the screen saver, but have the same results. Something is causing the last image to freeze on the screen when the monitor sleeps.

Background info:
A few weeks ago I upgraded from a regular macbook to a brand new macbook pro 2.66 ghz. I replaced the hard drive right away with a 500gb one (had it done by apple). So my machine runs snow leopard now, I used the data transfer mode to basicly copy the data and apps from my old macbook to the new MBP.
The "problem"
It all worked fine and smooth until a week ago ...For a week now I have a problem that really concerns me. Whenever I open my laptop from a sleep mode he gets really slow and unresponsive to my commands. Its like its crashing, all I can do to get out of this is a hard reboot.
However .. during a reboot OR a cold bootup the MBP gets stuck in the grey screen with only the apple logo .. after a minute or 3 it will start loading but it will never reach the login screen... The strange thing is that when I do reboot it over and over again .. it eventually will boot normally and when it does the MBP runs fine .. until I turn it off or put it in sleep mode .. then the nightmare will start again.
What I have done
I personally suspects the Hard Drive to be the culprit, I get the feeling that the Hard Drive is having trouble starting up or getting out of sleep mode. I am not sure tough.
I have done the following:
- Disc Utility (gives no errors)
- Booting up in terminal and run Disc Utility there (repaired a volume issue)
Could this be a leopard issue? I actually can't remember if this issue happened after the last macOS update or not ..I never had a problem with my iBook and Macbook so I have little experience on troubleshooting. So I hope you more technical experienced users can give me some tips on what to do here.

Maybe this is a dumb question, but it seems on my system if the screensaver runs then the monitor sleeps, the screensaver is still running when i go to wake the monitor. does that mean its been running the whole time wasting cpu cycles and drawing more power than is necessary? you'd think it would stop.

This must be new with SL but it is annoying me to no end... I like my laptop to require password after sleep, but NOT after the screen dims... I do NOT use a screensaver so I don't understand what is going on... any tips? I put the screen to sleep after 15 minutes and each time that happens, I have to enter my password to get back in.

Here's a weird problem I just got on a new (refurb) MBP.
Sometimes (not always) when I comeback to my MacBook after it's gone to screensaver then display sleep (though not full system sleep) the cursor is invisible upon wake.
I know the cursor is still there, but it just can't be seen on screen. If I go down to one of my hot corners, the associated action still happens (in my case sleep the display / activate screensaver -how ironic ), and if I roll over the dock I can bring it up and magnify the icons as I roll over them.... all with no visible cursor whatsoever.
In fact, I only get a cursor once I click on an app and either launch it or bring it up from being minimized / hidden.
This has never happened on any machine I've had before, but by all indications it's a software problem, nothing to do with the hardware.
It's a new 15" MBP 2.2 Ghz, 4GB Ram running Leopard 10.5.2 with all updates (even the recent keyboard update).
A search on this brought up someone else on another board with the same problem, but then the issue got clouded with discussion of dual-monitors or external displays (neither of which I use).
I'm going to go fix permissions right now, but I was hoping somebody here could ID this and help me figure it out.

I have a 24" ACD plugged into my iMac, and they work well together (other than the ACD needing a boost, but we'll discuss that some other time).
I can't seem to get backgrounds to stick; I set a background on both displays, but whenever the machine wakes up from sleep or a screensaver, it's back to the default nebula/star field of Leopard. When I try to once again set those displays, the folder containing the pics, which had been added to the preferences interface, has disappeared from that pref pane.

I'm downloading a long patch for World of Warcraft, and I want my iMac to stop burning up so much Heat! Can I 'half' turn it off or something - so that it keeps downloading but relaxes and cools down?

I'm running out of space on my Mac Mini's disk because of all my iTunes video files. I am thinking about buying an enclosure for my spare 1 TB hard drive, and using it as the location of my iTunes library, but I wondered how it works with the Mac Mini's energy-savings mode. My Mini is set to sleep after 15 minutes of inactivity, then wake when iTunes content is requested by my Apple TV or Airport Express. I like it, because it's very energy efficient that way! My question is, will the disks also sleep along with my computer, and will they wake properly when the computer wakes?

Everything is fine and great with my iMac 27 except for the fact that logging out and rebooting takes ages. I've already disconnected all 3rd party USB devices and logout/reboot times are still close to ~3 minutes.

I was talking to a friend last night and he was saying him mom had a 4 year old iMac that she had barely used. Her windows computer died and the local computer shop moved everything to the iMac and when the mom complained the iMac was slow the computer shop told her it had blown caps. To me blown caps wouldn't cause it to run slow, lock up and be unreliable I would believe but not slow. Has anyone had a Mac just run slow because of blown capacitors?

Recently I started suffering pretty bad from color wheel load time where safari was getting glitchy and taking forever to move. I tried to cold start it to see if a refresh would help. Well it white screened, and wouldnt exit the loading screen. I reset the ram memory with alt ctrl p and r; this did nothing. Eventually I kissed all my music projects and logic pro 9 good bye, and reformatted from the boot disc. When I went to use it, I got out of the white screen, but was ridiculously slow.
Thinking maybe I didn't do the partition right, I reformatted again, erased the entire drive, set the partition, and loaded 10.6. Any time I open safari, it gets glitchy, and incredibly slow to the point I cant even restart. I cleared the memory again and this still did nothing. I purchased and installed new ram; still nothing. Coming from windows a reformat usually takes care of things. I have no idea what I can do at this point. Its a 2007 24" 2.4 ghz 2gb RAM.

My iMac has been running very very slowly for about 2 weeks. I am talking very very slowly. It seems to be processing time. I will be in word, move the cursor and it will take a few seconds to get there. Sometimes I have to wait a minute after I click on something for the cursor to catch up, and (hate to say it) even 2 minutes. That's like a millennium in Mac time.

I have a 20" iMac mid 2007 2.4Ghz, 320GB, 2Gb machine running Snow Leopard. Today I turned it on and it was running fine. But around three hours of using it suddenly froze. I had to force the turn off using the power button. When i turned it back on it took about 4 mins to get to the login screen. Once I logged in the spinning wheel came up and the only think that loaded was the Spotlight sign. This kept happening until about the third time of turning it off and on. When it finally completed login. But it is now extremely slow and it just about freezes when I open more than one application.

I tried using a couple third party screensavers. Followed the instructions by dragging the .saver file into the screensaver folder in my library, but cannot retrieve the screensaver itself in system preferences.

Using 10.5.1, no problem up until now (new 2.8 iMac). Working all day with Adobe Lightroom 1.3.1, again, no prior problems.The computer froze, which I noted when the screensaver when I left to go eat dinner stayed static without fading out to a new picture. After force quitting and restarting, I went to the System Prefs and when I went to the Desktop/Screensaver section, I got a blank window. I confirmed all the other System Prefs icons work fine. It's as if the Desktop/Screensaver settings are erased/gone/whatever.

So my friend and I played a trick on an intern here at work who just got a new MBP. We swapped his background out for a vista one - real simple, right.
Well, he got back and had a good chuckle about it UNTIL - the system preferences panel crashed after he tried to switch it back.
So here is the only symptom:
Open system preferences
Click "backgrounds and screensaver"
window opens, looks ok
window closes and error screen pops up saying "system preferences unexpectedly closed"

When I choose the Desktop/screensaver option in the system pane, it unexpectedly quits. I can see that my screensaver is set to "Never". It will not let me click on "Desktop". To help trouble shoot the issue, I made another login account with the default settings - and the system pane works. I am able to test the screen savers, ect.Is there a way to copy the files/setting from the new login in to the old?

I purchased a lovely 27" iMac yesterday. I have installed Windows 7 64bit on it and apart from a few quirks everything is running very well.
One thing that is bothering me is the Windows7 screensavers and power-management... they never activate. The power-saving features of Windows 7 don't seem to work at all. I did an install using the new "late 2009" drivers on a USB thumb drive during installation of Windows 7 so I think I've done everything properly.Is there something else I need to do in order to access Win7's power management features ?
Also, I've noticed that the Mac drivers for the ATI 4850 onboard graphics do not offer me the full range of resolutions (there are only a few options at the moment, the full native res, 1280x720, 1920x1080 and 800x600). How do I get access to the full range of resolutions ? Can I install ATI Radeon drivers and use those instead of the Apple supplied drivers ?

I am running Mac Mini as a home server (turns out to be not a great idea, btw), and even though I set the preference to never sleep or shut down, it does go to sleep when there is no activity for long time. Since I am using it as home server, it should stay awake all the time or at least wake up from sleep when there is incoming ping from other computer, but it just goes to sleep.

So I've had my 24" Al iMac ever since November 2007, good and everything until the past couple days, after extended use of the imac, everything is fine, screen is great, but when entering screensaver, its still great, its like a couple minutes or so into the screen saver when the top of my iMac's screen starts to flicker! When I move the mouse to get out of the screen saver, every thing is back to normal. It happens with all screen savers.
