Today I am going to tell you some things to do when a Mac (with special attention to the Mac with Bluetooth keyboard) does not start and the screen remains blank “all the time” (stays on the screen in gray really although it could be called ” screen ” white “).
Well, a problem that you may run into someday is a pretty but ultimately irritating white screen (really is gray as I said before) that is the first thing that puts your Mac to start it so you know you have found out, that the monitor works and that is in it. Well, you have the white screen and you hear a typical sound that Mac OS X is booting normally. All right. In addition to that you can add a mishap and is that maybe you want to solve some type of problem that could have had, and you might want to start the Mac in safe mode or for example select manually with what partition or disk to boot the system (since you could have several options). But no, you can not even do that … As much as you press keys, that does not respond.
At that point, you stay looking at the screen waiting to see the little apple appear with the bite right in the center of the image ….and no, it does not arrive, Who will have eaten the apple that has not left or the remains ?. Obviously, there is some kind of problem and our patients may not be as long as the waiting time for an apple to appear on the screen, which seems to have been ” stolen “.
If we look at some specific documentation, we discover that any special key that is pressed when the Mac is started has a pattern to follow, and that is that it has to be pressed just after listening to the startup sound of the Mac and not before. Why? because the iMac, Mac Mini, Mac Pro usually all include a Bluetooth keyboard , and obviously, if the Mac has not activated the Bluetooth and is not ready to be used, there will be no keyboard, and therefore, it will not help to press any key (needless to say that the keyboard must be in condition and connected before starting the Mac). The solution is that the key is pressed when the Bluetooth it’s turned on on the Mac, and that happens, right after the startup sound.
Be the Bluetooth keyboard or not, it is already this a normal process established, pressing the corresponding special key just when listening to that typical boot sound.
Therefore, if the Mac does not boot it may be because the keyboard is not connected. Check the batteries, check that this is really on as it can lead to confusion by not having a ‘key pressed’ indicator. It seems silly but it is not. If the Mac does not find the keyboard is waiting to find it with the blank screen and the failure could be due to the keyboard itself or to the Bluetooth system of the Mac. At least make sure that the keyboard is in condition and with it continues to progress in other solutions.
If you have your Mac on a white screen and it does not happen there, you can do several things:
- Check the Bluetooth wireless keyboard. Make sure you are in condition.
- Wait for your Mac to give you an option. It may take a while, be patient and wait, the white screen is not so ugly in the background. The problem could also be in the partition or boot disk. Your Mac is looking for where to start and load an operating system, and cannot find it, so after a while without success, the Mac will put on screen options to boot. Act accordingly.
- Press the ALT key (option) just after listening to the boot sound and wait for a small menu to appear that shows you which partition or boot disk to start with.
- If you want to start the Mac in safe mode to check some parameter or similar, press the SHIFT key (capital letters) just after listening to the boot sound and do not release the key until you see the apple bit (the Apple logo) ) on the screen. Your Mac will take longer than normal to load since checks are made on the disks and unusual processes are done on your Mac. Be patient.
Surely the problem lies in the link with the wireless keyboard or in the partition (disk where to boot), so with these steps explained, you will exit gracefully. To solve any type of problem with the keyboard, check the level of the batteries (batteries). Make sure that the keyboard is perfectly active by checking that the green light comes on when you press a key just after turning on the keyboard.
To solve boot problems I recommend you review some of my recent tutorials where I explain how to make one or more partitions or create boot and emergency disks. Anyway, once the Mac in normal mode, go to the app ‘Disk Utility’ and make sure it is perfectly selected partition with Mac OS X as the boot (or you want to be the main and containing the boot operating system ). To do this, go to the ‘ Partitions ‘ tab (with the main hard drive selected) and select from the partition map, the correct partition with the main operating system.
