macOS ir­ri­ta­tions

Grap­ple with some com­mon ec­cen­tric­i­ties of macOS it­self

31 Speed up your sys­tem

If your sys­tem is run­ning slowly, save any open files, restart your Mac, and run a soft­ware up­date by go­ing to

> App Store > Up­dates. One com­mon rea­son for a slow sys­tem is hav­ing too many apps ac­tively do­ing stuff at once; try quit­ting a few of them.

Con­sider how many items are set to open at lo­gin, too – go to > Sys­tem Pref­er­ences > Users & Groups > [your ac­count] > Lo­gin Items to check and remove un­nec­es­sary ones. It’s wise to remove any items you don’t need. If this doesn’t have an ef­fect, try start­ing up in safe mode (re­fer to­cos­safe) to make sure third-party soft­ware isn’t re­spon­si­ble. Safe mode au­to­mat­i­cally scans and re­pairs cor­rupted sys­tem files on your startup disk, too.

32 Find a miss­ing file

If you’re sure you saved a file but don’t know where, click Spot­light’s icon at the top right to search for the file’s name – say, “va­ca­tion.” Al­ter­na­tively, press space­bar] and use the + (top right) in the win­dow that opens to add cri­te­ria to look for files by kind or extension, such as JPEG images or “jpg.”

If your file is still miss­ing, it may have ac­ci­den­tally been deleted. If you’ve been keep­ing Time Ma­chine back­ups, you can re­store items by fol­low­ing the steps at­timemac.

33 Fix fail­ing back­ups

If you back up your Mac with Time Ma­chine, you may see an alert say­ing a backup couldn’t be com­pleted. If you use an ex­ter­nal drive to back up, re­seat

34 Cor­rect the time

An in­cor­rect sys­tem time can lead to all sorts of is­sues with web pages not load­ing cor­rectly. To up­date this set­ting, go to > Sys­tem Pref­er­ences > Date & Time. Click the pad­lock at the bot­tom left, then en­ter an ad­min­is­tra­tor ac­count’s pass­word to make changes. Make sure “Set Date and Time Au­to­mat­i­cally” is checked, and that you’re us­ing your near­est time server – say, Ap­ple Amer­i­cas. Next, go to the Time Zone tab and se­lect your coun­try from the map, or use the Clos­est City menu.

35 macOS won’t start

If the op­er­at­ing sys­tem won’t start up, check care­fully for any er­ror mes­sages. A flash­ing ques­tion mark sig­ni­fies that the sys­tem soft­ware wasn’t de­tected, and may in­di­cate a hard­ware is­sue. Con­tact Ap­ple Sup­port if this hap­pens. If your Mac dis­plays a blank white or gray screen with a load­ing bar, remove any pe­riph­er­als and per­form an SMC re­set (see ap­ If startup still fails, con­tact Ap­ple Sup­port for fur­ther trou­bleshoot­ing. the con­nec­tion, click the Time Ma­chine icon in the menu bar, and choose Back Up Now to try again. If you’re us­ing a Time Cap­sule, up­date its firmware (see­tupd), then restart it. Make sure your Mac is con­nected to the same net­work as your Time Cap­sule.

36 macOS freezes af­ter lo­gin

Some­times your Mac will start up but then freeze on lo­gin. Its screen may even turn blue. If other users can log in to the Mac with­out any trou­ble, the is­sue

is most likely to do with in­com­pat­i­ble soft­ware or a cor­rupt font. You need to restart your Mac in safe mode (see­cos­safe), then go to Sys­tem Pref­er­ences > Users and Groups. Click your user on the left, then the Lo­gin Items tab to check for third­party apps that may be caus­ing this prob­lem. Also read­font.

37Force your Mac to shut down

On oc­ca­sion, your Mac will refuse to power off; if an­other user is logged in, macOS will prompt you to en­ter an ad­min pass­word first. If that’s not the case, you likely have a crashed app that’s stop­ping macOS from restart­ing. Save any files that you’re work­ing on, then click > Force Quit. Se­lect an app and click Force Quit, then try shut­ting down; re­peat if nec­es­sary.

38 Re­in­stall macOS

If your sys­tem is still be­hav­ing badly, you can try to erase the startup disk and re­in­stall macOS. To do this you’ll need to know the Ap­ple ID and pass­word you used to in­stall it. Make a backup if you can, then restart the Mac and hold at the startup sound. Fol­low the steps at­in­st­mac to set up as new, or­time to re­store from Time Ma­chine back­ups.

39 Re­set lo­gin pass­word

If you’ve for­got­ten the pass­word you use to log in to your Mac, the eas­i­est way to re­set it is to have an ad­min user do it for you. Ask them to go to Sys­tem Pref­er­ences > Users and Groups, se­lect your ac­count, then click the Re­set Pass­word but­ton. Af­ter re­set­ting your pass­word, you’ll need to cre­ate a new lo­gin key­chain – see­eych.

40 Fix the mes­sage “Your startup disk is al­most full”

You will see this mes­sage if there’s very lit­tle free space on your Mac’s main stor­age. In > About this Mac, click the Stor­age tab to see what data’s tak­ing up the most space. Click the Man­age but­ton to store some of your files in iCloud, remove watched movies and TV shows, and au­to­mat­i­cally empty the Trash each month. Ad­di­tion­ally, items in your Down­loads folder can usu­ally be safely deleted as you can of­ten down­load them again if needed.
