You must know your login password in order to log in. The login screen appears even if you usually login automatically. The next normal startup may also be somewhat slow. Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Start up in safe mode and log in to the account with the problem. The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.ĭisconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Don’t be disappointed when you find that nothing has changed after you complete it. Please read this whole message before doing anything. I imagine this is due to changes in the underlying window manager, but it seems as if Apple didn't realize or acknowledge that the behavior was going to look really strange or confusing on systems older than their current Macs - which includes a huge percentage of their user base. In many cases (Acrobat especially) the document window renders before the splash screen is ever drawn, so that all I get is the black window shown above for no apparent reason, and then the file I opened appears.

It would honestly be LESS jarring to just have the cursor spin for a few seconds longer, and have the window render correctly on first draw, than to have the current behavior.

some Office programs) are even weirder as the entire display goes black until the program window renders. Maybe it's just that the window is black, rather than empty or white, but it is jarring to have this appear apps that open maximized or full-screen (e.g. Just as an illustration, this is what I see when the Acrobat splash screen appears. I initially thought this was a display error caused by my ancient (2007) MacBook Pro, but I am still seeing the same issues on a newer (2012 unibody Core i5) MBP. Asking not because this is a problem per se, but because I cannot find anyone else mentioning this - all other 'black screen' or 'black window' problems refer to install hangs.Īfter the El Capitan upgrade, every new program window shows as solid black (with white corners) for several seconds (sometimes as long as 15-30 seconds) before the display kicks in and renders it correctly.
