I'm having an issue with my refurbished Mac, purchased in 2018 -
MacBook Pro (15-inch, Mid 2012)
2.3 GHz Intel Core i7
16 GB 1600 MHz DDR3
Intel HD Graphics 4000 1536 MB
... Basically, every so often, the left-click on the mouse stops functioning correctly and the right-click menu appears on screen instead.
When this happens, everything else seems to freeze, except the ability to move the cursor.
e.g. I'll be working in Logic, left-click to perform whatever action is needed
and suddenly the right-click menu - corresponding to the area my cursor is covering - appears.
If I switch to the trackpad, instead of the mouse, the same thing happens. At the same time, none of the keypad works and
I end up having to shut down.
Strange thing is, it's so unpredictable. Some days the glitch will appear within five minutes of start-up,
other times I can be working for hours on a project before it emerges ... some days it doesn't happen at all!
I'm concerned that it may be a hardware problem, as I've run first aid in disk utility, and have anti-virus software - both are all clear.
Any help would be much appreciated.
