My Imac(Intel) occasionally switches itself off. To bring it back to life I have to unplug it from the mains for a couple of hours. On plugging it back in the fan immediately starts up very noisily but nothing else happens. By holding down the on/off switch I turn the machine off. By pressing the on/off switch in the normal start up manner everything is OK.

This morning I turned on TimeMachine (I do a weekly back up) and it showed a back up would occur within the hour. When I went back to look an hour later it was set on off. I turned it back on and within a minute it turned itself off. I have a lot of memory available on my standalone hard drive so what the heck is up with this shutting itself off?

My iMac starts, takes about 10 minutes with apple logo & timer/progress bar then just switches off .. How to get it to the login screen?

Occasionally, this iMac starts, and it will say "safe boot" in the login screen, and I have not done anything to make it do that. I do not have a sticky shift key, as far as I can tell.

My 4/5 month old MBP has twice now "gone dead" and then just "come back to life". I'll just be browsing, nothing flash heavy and nothing else too taxing on the processor (email, itunes open but not playing, maybe text edit) and for no reason obvious to me the screen goes dead/black along with the back light on the keyboard dying. Then 2secs later the whole thing starts up again right were it left off, not a system restart like you might get if the battery dies, but the same way it would if you had physically pulled up the screen while it's been asleep.

I recently upgraded to 10.6.5 from 10.5.8. Ever since then I have had a problem with spaces. The problem is as follows:
When switching Spaces, there is the onscreen graphic along the bottom, telling you which space you just switched to. However, sometimes when switching spaces on SL 10.6.5, the graphic will stay there and wont disappear as it should. When it just stays there, the entire keyboard stops working because Mac OS X still thinks I am performing the Spaces switch. A logout is required.
I am running 10.6.5 with all updates applied.
I searched for this problem both on MR & on google, and although it seems that I am not the only one with the problem, I can find neither a cause, nor a solution.
My ibook g4 (about 15 months old) switches itself off when I move it. Then have to force turn off (holding start button down for 10 secs). I then have difficulty turning back on, in that most off the time the fan just starts, with no startup noise, and the computer just doesn't turn on except the fan. After a few tries it eventually works, but its hit and miss. Its my first mac and I'm really scared something major is wrong that will cost a fortune to fix?
View 5 Replies View RelatedI have Spaces enabled to provide 4 virtual screens. My problem is that I am in a Pages document, and I press Command-F to do a search. Spaces switches to a different virtual screen because for some reason it thinks the Find window belongs in another screen. The workaround is to move the document into the screen where the Find dialog opens. I suppose the cause is because Pages was originally opened in another screen, and moved, but the Find window thinks it belongs in the original window. Again, to me this is not a feature, but a bug.
View 5 Replies View RelatedI have a G4 800 powermac Quicksilver tower. I haven't used it regularly for a number of years, although it has been started up say every 5 months or so without any problems at all. Last weekend I started it up and it worked for about 2 minutes before suddenly shutting down, without warning. I tried starting up again and it started up, only to shut down as soon as the desktop appeared.
I started up again, and whilst the light in the power switch on the front panel illuminated, and a short 'apple boing' noise came on, it just shut down immediately after. Having left the computer untouched until the following weekend (today) the same order of events has unfolded. two minutes for the first go until unannounced shutdown, and then progressively shorter amounts of power. Whilst this isn't a critical piece of hardware for me, it does hold some useful data.
Safari switches sites on me randomly?

It started a few days ago.... suddenly, the Computer switches off and the Power LED blinks continues very fast.But at irregular times. It seem to me, when I am not working on it. (I have also connected a PC to the same monitor and keep switching the monitor).
Yesterday i was working all evening, and it did not switch off. This morning while start up it turned off.I checked the memory in My Mac and all 16 GB show up. after I push the power switch for a while and turn it off, I can boot up again (except this morning, where I had to restart after the crash)

Has anybody else been having a problem with the keyboard that comes with the new MacPros? I got the standard USB keyboard, as I need the number pad (although I'm finding that the cable really is a pain in the @#$@ and may go back to my old white plastic Apple Bluetooth keyboard) and every now and then it simply doesn't work.
Or rather, I will type and nothing will appear on the screen/be inputed into the document or text space.
I thought it was that it didn't like being hooked up via the USB Hub in my HP LP3065, but I'm finding it still happens now that I rerouted it to be hooked up directly into the front USB port on the computer. But the past few days it has resumed happening.
The odd thing is that if I change fields by clicking on a new area with the mouse I'm able to type. but until I do, nothing I type appears on the screen.
I'm not sure if it's a Microsoft issue (since I'm noticing it when I work on Excell and Entourage) or if it's merely that 90% or more of all typing I do is on a Microsoft product (Word Documents, Excell spreadsheets, Entourage e-mails...). I honestly can't remember if I've noticed this in Quicken (but I think it has).
Now close to once again fighting Apple in court, Mac clone maker Psystar has brought on a new legal team and has even begun steps to publish much of its knowledge about Mac OS X clones. The small PC builder on Monday was granted permission in a Northern District of California civil court to replace its existing legal team with the law firm of Camara & Sibley, a normally Houston-based team that required a pro hac vice order to operate outside of its normal jurisdiction. Why it's choosing new lawyers at this stage isn't fully evident. When it first mounted its defense, Psystar had gone out of its way to seek a legal team that had previously defeated Apple and which was an expert in intellectual property. Since then, however, the attorneys have had their counterclaims against Apple dismissed and were left in limbo when Psystar went into bankruptcy, putting a hold on the case until Apple had a stay on the case dismissed. Whether or not Psystar's previously non-payable debt contributed to the switch in lawyers is equally uncertain.
Now that the company is re-emerging, though, it's not only prepared to rely on new legal representation but on public support. The company sent an e-mail newsletter on Tuesday which promised an upcoming community page and a wiki page. The two would not only provide Psystar's own code contributions for running Mac OS X on non-Apple computers but planned to "explain and perhaps even standardize" ways of installing the software on any modern Intel-based PC. Not surprisingly, the same messages also reiterated Psystar's case for its potential customers and argued that, if anything, its business was doing Apple a favor. "We buy hundreds of copies of OS X legally, from retailers like Amazon and Apple itself," Psystar said. "We're probably one of Apple's biggest customers."
I have a late 2007 MBP 15inch 2.33Ghz Core 2 Duo. I have had since new and no problems. Over this last week I have had the same issue a couple of times. The MBP just switches itself off. The first time it did it, it was running on battery (I was using Aperture) and had 60% power available. It would refuse to re-start until I connected it to the mains and then it ran fine.
Then it did the same thing overnight at some point. I had left it connected to the mains (as I always do at home), had shut the lid to put it into sleep mode. When I came back it was switched off. No-one had touched it whilst I was away but yet it had just turned itself off.The only thing that I noticed was that when I started it up both times the little light on the magsafe connecter kept flashing between orange and green. However when the computer booted into OS X both times it showed a reasonable amount of power in the battery.
I noticed that my battery cycle (according to istat) switches over at 15%. So as son as it switches over to the next cycle I plug in the adapter to make the battery run a cycle from 100%-0.(I know the cycle in 100%) But it still switches over at 15%, that means that the battery ran only 85% of its capacity. How can that be? Is it possible to reset (delete) battery cycle data?
View 2 Replies View RelatedI am thinking of making the switch to a Mac, primarily because I am sick of Windows and PC's and all their shortcomings. I really cannot afford a brand new Mac, so I am thinking of ebaying it and going for a 2.4ghz early 2008 macbook. However, there are a couple of things I need to know:If the ebay product ships with software pre-installed on the machine, how do I save it in another location while I do a format and fresh install of Snow Leopard, and then load it back on without discs? I have heard that Time Machine backs up apps, but will it restore them to working order on the new install? (I'm thinking of software such as iLife and Office here)
Secondly, are the old style polycarbonate macbooks rugged in their design? I am careful with any laptop I handle, but I do travel with them a lot. I have had 2 dell laptops in my life, and on both of them the hinges and screen border have split right open after barely a year of use, as well as other issues such as audio failure, batterys, chargers and wifi not working right.
I have a dead/stuck pixel that one day can be green and one day be red. I dont really know what triggers it, if it can be some different colors I show on the screen? Anyway for hours and hours I've tried these websites that switches color several times each second claiming it will fix stuck pixels, but with no success. What can I do? I've heard that Macbooks have a "outer layer" of some sort on the screen, so you cant use the method to apply pressure on the screen, true? If is was just dead I would have no hope, but as it switches colors at least its alive.. Also, its really annoying as I've to always change background picture to hide the pixel
View 4 Replies View RelatedI have a 20" iMac G5 1.8 GHz which has been pretty reliable since new. A few weeks ago I fitted a new Hard-drive (Western Digital Caviar Black 1TB), other than that the computer is bog standard. For the last few days when I start up, the computer switches itself off straight away and I have to press start again. Sometimes it gets as far as the grey screen and sometimes it gets to a complete desktop screen before this happens. This may happen 2 or 3 times and then the computer works fine all day, I can even restart with no problems once it is running fine. As it stands I can live with the problem but I worry that it may get worse. Anyone know what this might be? Could it be related to the new hard-drive? Could it even be related to the cold weather?

View 5 Replies View RelatedStarts to power up from either mains supply or battery, but always switches off after anywhere from 10 seconds to a few minutes. Chimes, usually gets as far as screen coming on etc but then you hear the power cut and it just switches off (sometimes gets as far as login screen). Have tried NVRAM reset SMC etc.

Should I bother? I mean, won't I have to uninstall the ATI driver that bootcamp 3.2 installs and reinstall the driver I have now? I am not having any problems at the moment. Has anyone had any issues going to 3.2 with a 5870 after installing ATI's drivers manually?

I was hoping someone else has had a similar problem and figured out how to fix it. I was also thinking about taking it into Apple or an Apple reseller to get it looked at but I am not sure how expensive it would be.
Has anyone else ever notice that occasionally you loose all ability to scroll within Safari. The side scrollbar disappears and the mouse scroll wheel does nothing, despite there being more page to scroll down to. The only remedy I have found is to close out and reopen safari.
View 6 Replies View RelatedI've UNCHECKED the setting "Put the hard disk(s) to sleep when possible" because I find no value in this. Yet my second disk (HDD) occasionally spins down when the computer is left idle for a while. (My first disk is an SSD). It's all apple-made, no custom or user changes inside. It's not a big deal, but I know spinning down and up again adds wear to the disk and it's something I'd rather not have the disk doing.

My scroll bar is very undependable. Sometimes it works (moves), but more often it doesn't. I can usually get it to move after enough time and effort have been expended, but that's not the way it's supposed to work. I might add that I am frequently seeing the little "ball of death". One more thing: I have Smart Scroll installed, and it's not working properly either. It did, but not now.
