In general, no, it's not safe and I don't encourage it. You should be wondering whether you can believe me, and whether it's safe to run a program at the behest of a stranger. If you prefer, you can act on it yourself without disclosing the contents to me or anyone else. That report goes nowhere unless you choose to share it. All it does is to generate a human-readable report on the state of the computer. It doesn't send or receive any data on the network. Below are instructions to run a UNIX shell script, a type of program. There are ways to back up a computer that isn't fully functional. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not. The backup is necessary on general principle, not because of anything in the test procedure. If you don't already have a current backup, back up all data before doing anything else. You do harder tasks with the computer all the time.Ģ. The process is much less complicated than the description. It will do no harm, but it won't do much good either.ĭon't be put off by the complexity of these instructions. I don't recommend running it on older versions of OS X. The test works on OS X 10.7 ("Lion") and later. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. I have searched and no one ever mentions getting their desktop back (with the mouse) after it turns white, so not sure if it is the same problem as others.ġ. (I was given an old white iBook (2005?) after it my G5 died and the iBook literally went up in smoke in 2012-another display screen issue with the lid.) It died one month after the recall ended. I "lost" my old iMacG5 due to bad displays that were made in one factory in China back in the day. I have an iMac, 21.5 inch, Mid 2011, OS X 10.8.5 ,AMD Radeon HD 6750M 512 MB, 2.5 GHz Intel Core i5 At the time I got it, it was cheaper then buying an external hard drive as my other external HD was about to die any second. (I use the air port/time capsule not for an air port but for a storage for data and time machine data. Also my time machine decided there was a problem and erased all backups and started over. But the white screen that I can bring back by moving my mouse has been going on even after the updates, etc. After several restarts due to updates, it stopped being a problem.
(but everything was fine when it was loaded) and then to update it one time I had to restart it again this spring.and it started right up. (I would turn it off, then on, then off, then on to get it back) so left it on as I was afraid of it dying. Last winter, it wouldn't start up-it would take 10-20 minutes. There have been multiple "strange" things going on for awhile, none that are easy to figure out, like how my printer's preferences disappear and I have to remove it from the printer's list and add it back in (this has happened twice in the last week.). If I move the mouse or open a window and move it, then the screen "magically" reappears. For maybe 6 months now either when I reboot or come out of the "dictionary" sleep mode, my desktop is all white.
