MacBook Pro :: Random Clock Restart On Restart On Early 2009 MBP?

Feb 2, 2010

I restarted my computer, and when it booted back up the clock was reset to Dec 31 2000. I did not change the clock, and my control settings are password locked.

Should I be concerned about this, and has this happened to anybody else?

OS X :: Apple Grey Screen And Hangs, Gets To The Login Screen And Hangs?

Jul 13, 2010

I have a much loved ibook G4 14" (late 2004??). It has just died. Well, in so much as it won't boot up. The ibook either gets as far as the apple grey screen and hangs, gets to the login screen and hangs, actually loads up finder etc and hangs or none of the above. Sometimes flashing red, blue green black.

After lots of research online over the past few days I tried the following: I have tried safe mode (not working), starting the command prompt screen (single user and verbose modes), started open firmware, and tried booting from a CD. Nothing works as the boot gets so far then hangs. I have flashed the PRam, resetted the NVRam, and have stopped short of opening up the case to dismantle it!

I just really want to access the hard drive now. I have tried Target disk mode and linked the ibook (pressing T) via firewire to a PowerPC G5, but the G5 doesn't recognise the ibook. System profiler on the G5 shows the target mode connected and working fine via firewire, just the icon for the ibook/target doesnt mount on the G5 desktop so I cant access it.Currently the boot freezes within a couple of minutes.I tried the hardware test CD that came with the ibook years ago, I have also tried booting from an OSX Panther CD. I'm assuming they would be bootable.

I forgot to mention that in linking with the G5 in target mode, a disk that I put in the ibook drive appeared on the G5 desktop as an external drive, therefore I wonder why i cannot see the actual ibook drive mounted. The CD drive works as it mounted on the G5.Does the ibook have an actual PRam battery that can be replaced? Maybe this is an issue?Am I able to actually remove the hard-drive and access it as an external drive somehow?

Power Mac G5 :: Try And Restart It Switches Off But Will Not Restart?

Oct 7, 2007

I have a DP 2.5GHz PowerPC G5 which is giving me problems. It is on all the time (server). If I try and restart it switches off but will not restar. Also, if it crashes (only happens once every few months) then it will not automatically restart. I have replaced the internal battery but this has not helped. I have also reset the PMU. Any ideas what may be going on here?

MacBook Pro :: Periodically Hangs On Bootup

Nov 28, 2010

Every once in a while, my mid-2010 15" i5 MBP sits at the greyish Apple logo screen, after the "bong," with the wheel spinning forever. If I shut down and reboot, I'm at a log-on screen in about 15 seconds (which is my typical boot time, as I have an SSD). This is my first Mac after a long time on PCs, so I've got no idea where to start. All the posts I've found by searching pertain to earlier model machines using HDDs where the user can't get a boot at all; I'm only seeing this weirdness periodically.

MacBook Pro :: HDD Keeps Stalling - System Hangs After Sometime

Jan 12, 2010

7200rpm SATA disk (custom config when ordered uMBP) keeps stalling (beach ball) every so often. I used Disk Utility on my uMBP and it was corrupted so I repaired it and my system still hangs every 15-20 minutes. It does this no matter if I'm launching an app or just doing nothing. So I formatted my drive and reinstalled OSX Snow Leopard. It seemed fine but now it's doing it again. Using Disk Utility shows nothing wrong with the drive this time. I'm still under warranty but I don't want the downtime of taking this in.

Safari :: 5.0.6 Hangs Or Less Responsive On MacBook

May 1, 2012

I am running Safari 5.0.6 on OSX 10.5.8. I have had this problem for the past year and has become gradually worst, on 2 separate machines. I have resetted Safari numerous times, I have repaired permission, re-booted computer, and as suggested by a Genius at apple store, re-booted in "safe booth" to clean up stuff. It appeared to work for about 1 month, until it slows to a crawl, and become unresponsive.

Problem is now it does not seem to cut it anymore. I performed all of theses operations on both My desktop (power PC G5) and my laptop Macbook (intel) again yesterday. On my desktop, Safari is working marginally, but on my laptop it is not at all. The laptop is a more recent machine, but is less responsive. When I use other browsers, like google chrome or firefox, I can surf the web no problem. How to clean Safari up to run anew again.

MacBook Pro :: Yosemite Hangs After An Hour

Dec 11, 2014

URL....I had a troublesome upgrade to Yosemite on my 2010 MBP with a custom 128 GB SSD installed. I had to abort installation and then recovered from that by reinstalling OSX via recovery mode. Now everything works fine except for the fact that the system freezes (spinning beach ball, can move windows, cannot access force quit or change focus) consistently one hour after boot. Even after several hours nothing happens and the only option is to hard reset. Booting in safe mode has the same effect.

any problems in the system logs, and after a forced restart, no crash report is generated. I don't know what happened for the user in the linked thread, but our issues seem quite similar - what could this be? Some kind of daemon blocking after one hour?

Info:
MacBook Pro, OS X Yosemite (10.10.1)

MacBook Pro :: Installing Second Drive SSD - System Hangs

Dec 6, 2010

I have a 13" mid 2009 MBP and due to issues with the superdrive I decided to buy the OWC data doubler kit and install it with a 120GB SSD from them. I also upgraded to 8GB RAM at the time but I do not believe that has anything to do with this. After I did this, my original HD freaked out and wouldn't even show up in target disk mode. Eventually I made a clone of the Snow Leopard install disks onto a USB stick using a friend's laptop and installed OSX fresh onto the SSD. Luckily I had a backup of everything so I have not lost anything. Even with the fresh install, however, I am having a lot of issues with the OS. When I try to boot the machine, it often takes 3, 4 or even 5 times to boot normally. As far as I remember, booting into safe mode works right away but that is obviously not a solution. Usually it starts by hanging at a blue screen once or twice, then I can get to the login screen but it is either kind of grayed out or it just freezes and I can't even move the mouse to type in my password. When I do safe mode it boots up without this issue, but even after that I often see the computer freeze up during use, which happened the first time I wrote this post. This problem also occurs when waking up from sleep. If the laptop goes to sleep by itself or I close it, I have to power cycle it to return to use. The keyboard will light up, but the screen never comes on so there is no way for me to log in. These issues are extremely frustrating and make me feel dumb for doing this in the first place, considering that everything worked ok before(minus the superdrive). Has anyone seen these issues before? Resetting PRAM and booting into single user mode are not helpful, I have tried them many, many times and I see the same issues. I saw somewhere else that I should try to remove the fonts, startup items, and loginwindow.plist files/folders and put them on the desktop, but even after doing that the issues persist.

OS X :: MacBook Printing To Network XP Printer - Hangs On

Nov 3, 2008

I'm trying to connect my leopard macbook to a Canon Pixma MP210 that his hooked up to an XP machine. Sharing is enabled in XP on the printer and I can successfully add the printer to the mac in system preferences. I've downloaded the proper drivers from Canon's website and selected them for the printer. The problem is that when I try to execute a print job, the print queue comes up and hangs on status "printing."

Also, on the XP machine, the print queue recognizes a job is being requested but the status hangs on "spooling." The document never actually prints. Finally after a couple minutes, the print queue in the mac has an error stating: "Error Number : 311 Printer is in use or an error has occurred. If an error has occurred, eliminate the cause of the error."

MacBook :: Hangs With Weird Intermittent Sound

Sep 11, 2009

Ok, this is kind of hard to describe without a recording of it but my MacBook has this frustrating fault where it beachball's without warning and produces a really hard to describe sound every few seconds. The best I can come with to describe it is an "uh-oh" sound from around the keyboard area. It hangs like this for anything from 2-10 mins and will be pretty much unusable in that time.

MacBook Pro :: Retina Hangs In Iphoto 3 Minute?

Jun 19, 2012

My shiny new retina macbook pro took 11 hours to transfer all my files over wireless to the new machine. I thought all software was current, and everything seems to be there.  

When  I opened iphoto for the first time, ...I  cannot quite remember the message , but do remember it said  iphoto needed to update and it would take about 3 minutes ??  

Well iphoto has given me the grey screen of death. I can see the side bar that is empty and the empty screen in the middle. I left it overnight and it was the same. My library is about 50 GB. I force quit and it now has a progress bar and is now stuck at step 5/  95% for another 30 minutes.

MacBook Pro :: Hangs After Disconnecting From Dual Thunderbolt

Sep 4, 2014

I have a dual Thunderbolt setup (chained).  When I disconnect my Macbook Pro (Early 2013, Retina 15", 2.8 GHz, i7, 10.9.4 (13E28)) and open the lid, the display back light comes on but the screen remains black. I can hit caps lock and the light toggles.  But, I never get beyond the black screen to a login.  I need to do a hard reset (holding down power button) to recover every single time I disconnect from my displays.

Mac Mini :: Restart Message - Hold Power Button / Press Restart Button

Apr 29, 2009

I have just shipped my Mac Mini to its new home and I've had reports that the panic error is appearing on boot up: "You need to restart your computer. Hold down the power button for several seconds or press the Restart Button." This screen appears on the blue window just after the grey apple screen has disappeared and does not get as far as the desktop at the same point each time. We have tried to reinstall mac OS from the original install disk but holding the "C" Key or the "Option" Key down on restart doesn't boot from disc. Is there a way you can view the Kernel Panic log before you boot into Mac OS so we can try and pin point the source of this problem. I'm wondering if this could have been the result of the shipping that has caused some hardware to come loose.

MacBook :: Hangs On Gray Screen - Apple Care?

Mar 26, 2009

A friend of mine has a black MacBook and it stopped working. When I switch it on there is just a grey screen with the Apple "doing" but then nothing happens. I tried some key combination to reset the NVRAM but it didn't help. The MB was purchased around 2 years ago with the Apple Care extension of + 2 years so it still should be covered by Apple Care. My questions concerns the Apple Care since I don't know how it works: - my friend says that he just bought the Apple Care extension when he ordered the MB and that"s all. Does it need to be somehow "activated" so that the MB is covered ? He has the Apple Care box but he never opened it. - Does he need the MB order bill to make Apple Care work ? - The MB was purchased in France but he's now in Germany. Can we just bring it to a Apple store here?

MacBook Pro :: Hangs On Boot Process After Win7 Install

Jul 6, 2009

I have a (check sig) and just tried to install the Windows 7 RC 64-Bit onto a Bootcamp Partition. I had been using the Beta way back, but had cleared that partition in advance for a clean install. With that I had no problems...ran the 7 beta fine alongside OSX. I followed the same procedure I had done for the beta install with RC, following the guide on the internet. Everything seemed to work out peachy, Windows 7 booted fine, I added all my settings again. Then I switched over to OSX to eject the disc, which was fine although the boot in was quite sluggish. I set the boot drive as "Macintosh HD" in System Prefs, and proceeded to try to boot into Windows 7 again....this time it was no go.

The screen came up with the white cursor on black, and then the "Starting Windows" showed, with the animation above it. At some point during the animation, it just froze. My fans were at normal speed and everything. I tried many times, same story. So I thought I would shut down, boot into OSX, and try to erase the partition. That didn't work either. When booting into OSX, the start-up chime sounds with the white screen, then the gray Apple logo shows up....and that's where it stays. I reset the PRAM, no luck. What could be the reason it hangs on BOTH boot processes? Because for a short time they did both work, and I could not have erased my OSX partition or anything because I did boot into it once after installing the Win7 RC. I also can see both partitions when I boot holding Option...

MacBook Pro :: Wired Internet Connection Periodically Hangs

I purchased my new mbp a little less than a week ago, and Ive noticed a slight problem. Normally my internet is blazing fast, but every once in a while (every 3-5 hours) my internet will just stop for about a minute.
