The PRAM has been reset only if you hear the Mac reboot sound a total of two times – once for the initial reboot and again when the PRAM has been reset (technically you can keep holding down the key combo and reboot the Mac over and over, but there is no practical reason to do so). In rare cases, your Mac might encounter an unrecoverable issue affecting all open apps. When this happens, your Mac must be restarted. This is sometimes due to what is known as a 'kernel panic' because an underlying part of the operating system (the 'kernel') has determined there is an issue that requires a restart.

I went to the Windows Update site, and there were updates waiting. I downloaded and installed them, then Windows Update would start an install and install the updates again. Microsoft support had me re-install SP2 without cleanup, then my computer would restart without warning every time there was an update.

You’ll need to be connected to the internet, as the tool will download the operating system from scratch. How to insert date in word. Check for Other Warning Signs on Mac All Macs, whether a high-end MacBook Pro or an older iMac, have great reputations for reliability.

Is your Mac acting just odd? Stuff like drives not appearing, screens not adjusting correctly, Bluetooth problems, AirPort non connecting? Maybe your fan is running non-stop or your battery has said that it is 50% chargedfor two daysand your MacBook is plugged in. Yeah, these aren’t problems that simple rebooting often fix. And while doing stuff like fixing permissions can fix some strangeness, this is strangeness on a deeper level. This is hardware strangeness.

When Apple launched iOS 7, it bet big on a completely redesigned and reimagined flagship product. Many of the changes and additions were greeted with praise, but bugs in, iCloud and other features plagued the mobile OS since release. One of the more pervasive —and concerning —issues involves reports of continual crashing during normal use, which sees devices randomly conduct soft restarts for no apparent reason.

This is one of the most common causes of system freezes, but the computer usually resumes without a catastrophic failure. Adding more system memory is one of the best things that you can upgrade, giving your Mac the best chance of performing well. It will also allow you to open more simultaneous applications without noticing any slowdown. Perform Regular Housekeeping Your Mac will generally run OK by itself with few serious issues, but when applications or the OS itself starts to freeze or crash it’s recommended that you invest a little time in sensible housekeeping duties. A few activities you might consider are: • Defragment your hard disk, especially if you use massive files such as video. Applications such as and are good third-party tools to defragment a Mac’s disk • Verify and repair disk permissions using the built-in Disk Utility tool • Delete unused applications and clear out their preferences and system caches • Empty application caches (e.g.

Recovery Console Launch Recovery Console by holding down 'Command-R' while booting your computer on Mac OS X Mountain Lion and Lion. When you are presented with a list of options, select the 'Reinstall OS X' option and follow the prompts to reinstall your operating system while preserving your data. You should create a backup image of your computer by launching Disk Utility from the list of recovery options, select your hard disk and then click 'New Image.'

Click OK to send the report to Apple, or close the window to dismiss the report. If the issue doesn't happen again during the next few weeks, the issue is likely resolved. OS X Mavericks helps you correct kernel panics related to software you may have installed.

SMBIOS: Mac Pro 5,1 (mid 2010) - I also used iMac 14,2 and iMac 15,1 with the same stability and mentioned problem. OS: SIerra 10.12.5 (16F73) - Also use many previous versions. Nvidia web driver: 378.05.05.15f01 - I realized that these drivers are created for Mac Pro 2010, that's why I chose my SMBIOS Cuda: 8.0.83 I have 2 monitors connected, the main on the first DVI port and second with HDMI.

The screen has no apple logo or loading bar. Since you are talking data recovery now, until you get all your data back DO NOT WRITE TO THE DRIVE YOU ARE RECOVERING UNDER ANY CIRCUMSTANCES, EVER, OR YOU WILL LOSE ANY AND ALL DATA ON THE DRIVE WITH ABSOLUTELY ZERO CHANCE OF RECOVERY!!! If you really want to play it safe you should send your drive to a data recovery service. Those are expensive but you have a better chance at getting your data back. A good data recovery service can not only get data out of a drive with messed up metadata, but also a drive suffered from mild to medium damage. The best bet without contacting a data recovery service is to boot from another device and image your drive off to another storage media.

It seems that Logic forces the use of the discrete NVIDIA GeForce GT 330M graphics card. My MacBook 6,2 runs beautifully, otherwise.

My 13' MacBook Pro 2010 running Yosemite suddenly stopped booting today. After I press the power button, I can hear the chime and the computer proceed to go to a blank gray screen immediately.

Mid-2010 MacBook suffered what seemed to be a too fast battery discharge on normal usage. Changed battery, new one appeared to have low capacity value. Changed for another new battery, seemed to have greater capacity (according to System Parameters software) and much greater discharge time. Went through Battery Calibration process. All seemed well. Installed remaining battery screws and back cover. Tried to start up; nothing.

Here's how to do it. Have one end of the fire wire cord connected to the frozen laptop; turn it on while holding 'T' until you see a symbol that moves around on the screen then let go. Then plug the other end of the fire wire cord into a healthy mac and you should see your frozen mac in finder as a hard drive. Copy paste or drag and drop your files until you are satisfied you have everything you need. Disconnect by clicking the arrow beside the name of the laptop (now a hard drive). Proceed with restoring your frozen laptop.

As of iOS 7, iPhones with black faces show a black screen with white Apple logo, while those with white faces display the inverse. Illustrating the extent of so-called 'white/black screen of death' problems, the publication points to an Apple Support Communities filled with similar complaints. As of this writing, the 'iPhone 5 with iOS 7 randomly shuts off' thread contains 249 replies and over 89,000 views. In most cases, users affected by the crash see a sudden and seemingly random reboot sequence. The cause of the soft restart is unknown, though some forum members claim the issue presents itself more frequently when power levels are below 30 percent.

This also gives a chance for daemons and other background system processes to reinitialise, which can sometimes resolve any issues. You don’t need to restart your Mac every day, but once a week seems like a sensible compromise. Note that starting a computer actually increases the strain and wear and tear on its components when they transition from an unpowered to fully powered state, so it’s probably a good habit to leave your computer in sleep mode rather than turning it off completely (and it’ll be ready to use more quickly). Free Up Some Hard Disk Space Mac’s don’t like operating with hardly any free disk space, so make sure you have ample room left on the drive. If you have almost no space left it will certainly increase the frequency of system slowdowns and freezes. A few tips to free up some additional hard disk space are: • Find and remove duplicate files using applications such as and • Regularly empty the Trash and individual application’s Trash cans (such as iPhoto and iMovie) • Find and delete (or archive) very large files such as videos and photos • Compress, move or archive old files and emails • Move your documents to a cloud-based service such as iCloud or DropBox.

But in fairness to them, they have given me the opportunity to get it sorted at an AppleStore through the proper channels - this will probably be my next route - trouble is, i don't want to be without this machine. Sorry i can't offer any further solution, but just thought you'd like to hear a slightly different set of circumstances to the same problem. Good luck everybody.

This will immediately isolate the problem as being the RAM, or eliminate it as a culprit. I don't know if your Mac Pro has one or two riser cards, and whether it will boot with only 1 riser card (if you have two cards) but it can't hurt to try. It is an easy thing to try, and may indicate or eliminate the riser cards. The trick is to change one thing at a time, starting with the easy stuff. With computer HW problems you don't usually 'find' the problem so much as eliminate all the other possibilities. You start with the easy stuff, and methodically go through every possibility.

Every time I start my computer I make sure that the app is enabled and force my computer into Intel Only mode. I have issues when it is in the dynamic switching or Nvidia modes. I am able to still perform all of the functions that I originally used the computer for, granted I never used it for video/photo editing.

The next action I did was to choose “Startup Disk” where the only option was “Mac HD”, rebooted and again logged on normally. Hope this helps someone.. Final thought..

Especially when it comes to the following models, for which: • MacBook Pro (15-inch Early 2011) • MacBook Pro (15-inch, Late 2011) • MacBook Pro (Retina, 15-inch, Mid 2012) • MacBook Pro (17-inch Early 2011) • MacBook Pro (17-inch Late 2011) • MacBook Pro (Retina, 15 inch, Early 2013) After hours and hours of research and calls with Apple, I actually found two quick fixes that might even do the trick for you. Reset SMC to fix battery and other hardware problems The System Management Controller (SMC) is responsible for a number of hardware inside your MacBook. It controls everything from all the lights in your Mac, the battery, fans and parts of the logic board.
