Freezing Issues with macOS 10.12.3

[adrian451]

I am currently in contact with Apple concerning this and as of this present time, they are being helpful, but it is clear to me that they are as yet unwilling to admit there is a problem.

It appears to have all the signs of a memory leak. The imac will freeze at any given point with no warning
examples with multiple apps open or just one or even when computer is idle with nothing on the surface open. Suggestions were to screen grab activity monitor, however rather difficult when the whole computer has frozen.

Other suggestion run in safe mode, not helpful as I cannot use various items such ext Mic as it does not recognize it. I am beginning to feel I am going round in circles, I also notice that applications take longer to open than previous version

The reason for upgrade was to remove that annoying issue with wifi dropping off for no reason wish I had never upgraded, that was a minor issue compared with this. Now the computer is as reliable as a PC very sad!

Sounds more like faulty RAM, not a memory leak. That would slow down the computer but not downright halt it. Try running the Apple Hardware Test: https://support.apple.com/en-gb/HT201257

Safe mode is meant for diagnosis: if the issue doesn't manifest on safe mode, chances are it's done third-party (not Apple's default) device driver or app that causes this.
