How to ..

It Starts But Runs Really Badly...

Do you get the multi-coloured 'spinning wheel of death' regularly? Is the whole thing running slowly? Does it take forever to open webpages or to open any file at all? These are symptoms of an unhappy computer, the cause can be various things.

The first thing to do is some basic trouble shooting and maintenance, beginning with a
Restart and Zap the PRAM:
(Parameter RAM is a cache where settings are stored which can become mildly corrupt and cause problems. Some minor glitches can be sorted by clearing it — zapping it)

1. Restart, and as soon as you hear the start up noise immediately hold down the 4 keys: Apple+Option+P+R on the keyboard.

2. Wait until the Mac makes a second start up noise a few minutes later, keep holding until it has made 3 extra start up noises then let go all the keys and it will strat up as per usual.

3. When it has started up go to Applications/Utilities and open Disk Utility. Select your hard drive icon on the left and click the button called Repair Disk Permissions.


Further Troubleshooting:
After all that if there is no improvement you will need to one of two things:


1. On older computerslocate the install disk that you received with the computer. If there was more than one disk it is Disk 1 that you need.

Pop it into the machine and Restart the computer from the Apple menu top left and as soon as it goes black before it boots up again hold the C key down. This will tell the computer to run from the operating system on the disk rather than the operating system on the computer, so that diagnostics and repair can be attempted on the internal hard drive.


2. One current and recent computers with no disk, Restart the computer from the Apple menu top left and as soon as it goes black before it boots up again hold the Command and R keys.


1. On older computers, the computer will start and eventually offer a page that prompts you to choose English as your language. Next page will say Preparing for Installation. Ignore it and go up to the Utilities menu at the top of the page and choose Disk Utility. It will open same as it did on the computer when you zapped the PRAM in the previous step, but this time it is running from the disk so it can Repair the hard drive which is currently not being used. Image below.


2. One current and recent computers the computer will start and eventually offer a page that prompts you to choose English as your language. Then you will get a choice of a few options. Select Disk Utility:



Once you select the top icon for your hard drive on the left of the window the button on the bottom left called Repair Disk becomes active. Click it and the utility will Verify and Repair the drive if it can!
Usually there are only minor repairs required which you will see as red text in the repair window and it will fix them OK.
If the Repair Disk Permissions button is active, click that after the Repair Disk has finished and wait for it to complete as well.
If the damage is too severe Disk Utility will inform you that it can't fix the problem and will recommend a dedicated repair utility like Tech Tools Pro or Disk Warrior.
Once it has finished, quit Disk Utility, quit the installer (Command+Q) and choose Restart from the Options offered and the computer will restart as normal.

It Starts Up But Has a Question Mark Instead of the Desktop!

The question mark means Where is the Operating System? If the computer boots and the hard drive has problems you will get this symbol and it usually but not always means a physical problem with your hard drive. First thing to do is follow the procedure in the previous page It Starts Up But Runs Really Badly and boot the computer from an install disk.
When you open Disk Utility if instead of a hard drive icon on the left you just get an empty window then you now your hard drive has major problems and it is at this point you rejoice as you remember that Time Machine has been backing up your computer every hour, hasn't it?! If so it is an inconvenience rather than a major catastrophe as new hadr drives are quite inexpensive. You have a new one fitted, boot off your install disk and from the Utilities menu choose Restore From Time Machine Backup. A couple of hours later your computer is back as it was before the problem.

Sometimes it is some other hardware problem that is causing the issue such as a logic board (mother board) which needs attention and will mean a trip to your local Apple Mac repair shop. here in Byron Shire ours is Lightforce.

It Won't Start Up!

If you press the start button on the computer and nothing happens at all then, Huston, we have a problem!
Check that all the cables are pressed in correctly make sure that you have mains power at the socket you are using by plugging something else into it to test it and try again. If there is a noise or a light comes on but still nothing further first try the steps in It Starts But It Runs Really Badly. If you still get no further after all this then you have a hardware problem and will need to take a trip to your nearest Apple Mac repair shop. Here in Byron Shire it is Lightforce.

There is not a lot you can do if you have a hardware issue like this. What you can do is eliminate all other things like cables and connections so that you don't drag it down to the shop and find that it starts perfectly! This does happen...
