Search at the site for previous editions that might work. Not all softwares will work on all versions, especially on older equipment. As a side-effect: It can show you battery condition of attached devices like iPads, iPhones, etc. So also look at the other info on the screen to tell you current consumption and charge level. So it won’t run so long off its cable- But can result in current surges causing reboots, etc. It shows you now only the CHARGE level of your battery- which is what you see on the menu bar anyway- but more importantly its capacity to HOLD charge, which decreases with age.ġ00% when new, after a few years when this drops below 80%. Recycled Parts are available on eBay, etc. Your cooling fans may be blocked, jammed or otherwise failed. This utility checks fan speeds AND temperatures: This will bog down your MAC as it throttles back its CPU and GPU to prevent damageīlow dust out with compressed air or a cleaner can of air. If it DOES there is likely dust in the vents or failing/failed fans.

The average MAC has several temperature sensors on the various hardware: CPU (Important!) battery, hard drive etc. Unplug it for now.īuy a spare 1TB USB device from Amazon & use that first- Reason is, in some circumstances, the backups may be readable but not writeable- Reformatting it and re backing up is a Plan, but would leave you with nothing for a while, especially if it refuses to format, hich is a real test of mechanical problems. Warnings that Time MAchine cannot write to the drive or that it doe snot even show up are a clue. Unplug the device to see if the Slowdowns cease. Generally this is a USB device which is NOT easily detected with DriveDX but could be to blame- Errors in external storage devices can slow down the MAC resulting in “BeachBall Of Death” spinning wheels. Note that there is no reason NOT to be using “Time Machine” for MAC BACKUPS.

This is NOT something “Disk Utilities” can fix.īut if you get a Green, no reason not to run that now. No need to install the “Monitor” phase if it asks during install.Īnything but a green result is cause for some concern especially if a RED warning comes up- a BIG concern! But read on about Temperatures. The Trial Version runs 14 days, enough to figure out if you have any problem NOW. it’s a small download and is easy to install.

Older: HDD (Hard Disk Drives) and newer SSDs (Solid State Drives) can be diagnosed with DriveDX at this link. MOST but not all issues trace back to hardware on a MAC.īut the built in diagnostics are not very good. MAC software (Named OSX) is incredibly reliable and secure, but relies on underlying hardware to work right.
