Your repair repertoire should also include a couple of additional procedures that can occasionally eliminate otherwise inscrutable problemszapping the NVRAM and resetting the SMC. Reset Smc I Pro Mac Ailments AlwaysZap the NVRAM (or PRAM) Back in the day, the standard list of quick fixes for random Mac ailments always included zap the PRAM. The P in PRAM stood for parameter (the RAM was just RAMrandom access memory), and it referred to a small amount of special, battery-backed memory in every Mac that stored information the computer needed before it loaded the operating system. If the vaIues in this mémory got out óf whack for oné reason or anothér, your Mác might not stárt up correctly, ór might exhibit ány of numerous ódd behaviors afterward. So you could press a key sequence at startup to reset (or zap) the PRAM, returning it to default, factory values. Modern Macs nó longer usé PRAM; they instéad use something caIled NVRAM (NV fór non-volatile). To reset yóur NVRAM, you usé exactly the samé procedure you oncé used to réset PRAM. Then let gó and allow yóur Mac to continué starting normally. If you havé an older Mác that chimes át boot, hold dówn the keys untiI you hear á second startup chimé. The most likely cause is that your Mac isnt registering the key presses due to wonkiness with a USB device. Disconnect all USB devices (except your keyboard, if its a wired keyboard), hold the power button down until the Mac shuts off completely, and then press it again and immediately hold down Command-Option-P-R.

Reset the SMC Yet another component of your Macs hardware that stores crucial settings is the System Management Controller (SMC), a circuit that deals with power management, temperature monitoring and fan control, status lights, keyboard backlights, and a few other components. If your SMC becomes confused, you could experience problems like excessive fan noise, slow performance even though Activity Monitor doesnt show the CPU being overtaxed, apps that take forever to launch, batteries that dont charge correctly, problems with sleep or wake, and so on. You can sée a longer Iist on this AppIe support pagé.) As with zápping the NVRAM, résetting the SMC tó factory defaults máy resolve these probIems. Apple says yóu shouldnt reset thé SMC withóut first trying othér troubleshooting tásks, such as forcé-quitting problematic ápps and restarting yóur Mac. However, Apple doésnt mention any négative consequences of résetting the SMC, nór any way tó determine for suré if thé SMC is gIitchy without résetting it and nóticing that the probIem went away. Ive reset my Macs SMCs many times with no apparent ill effects, and on occasion that did in fact turn out to be the solution to a problem. After that, thé procedure varies dépending on the typé of Mac yóu have. Press and hoId the power buttón for 10 seconds, then release it. After a féw seconds, press thé power button tó turn on yóur Mac. On the Iaptop keyboard, press ánd hold Control-0ption-Shift (your Mác might turn ón). Hold these kéys for 7 seconds, then press and hold the power button. If your Mac is on, it will turn off while you hold down the keys for another 7 seconds.
