 Hi Tim
 
 When you removed and replaced the RAM, did you put it all back or test it 
 separately?
 That would be one check, is just run it on one stick of RAM at a time. It 
 will be slow, but this can narrow down if a stick is faulty.
 
 Also, you can check the drive as well to ensure that’s ok.
 I recommend the following SMART Utility. (You can run it in Shareware mode)
 https://www.volitans-software.com/apps/smart-utility/
 This will check the drives and advise is “Passed” (green), “Failing” 
 (orange) or “Failed” (red). It works with Fusion Drives as well and will 
 test both HDD and SSD separately.
 I’ve used it to find faulty drives even before Apple Disk Utility finds 
 them. So it’s a good little tool.
 
 That would be my first things to try anyway, just to rule out a stick of 
 RAM and drive is ok.
 Also try an SMC reset and PRAM reset. (I have steps on my FAQ page of my 
 website if you’re not familiar with that.
 
 Try those and see how you go.
 If no success, and seeing you’re up Duncraig way I’d recommend MacWorx 
 Joondalup. (Delage Street, Joondalup) - www.macworx.com.au
 
 Hope something there helps.

Re: iMac random restarts

[Daniel Kerr]

Hi Tim

Generally I use the bottom slot, as that tends to be the first one it checks. 
(And Apple ship in the bottom two by default,..so I assume that first one is 
the first one it checks).
Kind regards

Re: very puzzled.

[Peter Crisp]

Hi Daniel and Rosemary, I have a free web app Disk Inventory X - it is very 
good at showing you where everything is. It is amazing the clutter that can 
build up - and this application presents in a nice user friendly way to drill 
down the levels to see what junk is cluttering up your drive. When you get it 
and run it - you must give it a bit of time to scan the selected drive before 
you’re presented with the representation of all the stuff you have.

At the same time a lot of caution should be taken in not indiscriminately 
deleting stuff you need to keep - especially system related. 

Pete.

Re: very puzzled.

[Daniel Kerr]

Hi Rosemary

That “storage” part can sometimes get a little lost, so it just dumps things 
into one spot.
Best way is to have all the folders in List View and turn on “Calculate All 
Sizes” (from View menu - Show View Options.
Then let it calculate folders. You can then narrow down where a lot of space 
may be used.
(Some can be in hidden folders as well, especially if you have back ups of 
iPhones/iPads etc. (and old models, as it saves them all).
Also, if you have iPhoto Library and Photos Library  (in Pictures) then this 
can take up more room than needed.

That’s a fairly “quick” way to get a rough idea of where it may be. Then can 
work through it.
(Sometimes not always an easy thing to narrow down straight away).

Another Application that can help with it sometimes is WhatSize - 
https://www.whatsizemac.com
(But you have buy it to get all the feature set, so sometimes the free trial 
only gives you a rough idea of space).

Hope something there helps.
Kind regards
Daniel

Re: iMac random restarts

[Daniel Kerr]

Hi Tim

When you removed and replaced the RAM, did you put it all back or test it 
separately?
That would be one check, is just run it on one stick of RAM at a time. It will 
be slow, but this can narrow down if a stick is faulty.

Also, you can check the drive as well to ensure that’s ok.
I recommend the following SMART Utility. (You can run it in Shareware mode)
https://www.volitans-software.com/apps/smart-utility/
This will check the drives and advise is “Passed” (green), “Failing” (orange) 
or “Failed” (red). It works with Fusion Drives as well and will test both HDD 
and SSD separately.
I’ve used it to find faulty drives even before Apple Disk Utility finds them. 
So it’s a good little tool.

That would be my first things to try anyway, just to rule out a stick of RAM 
and drive is ok.
Also try an SMC reset and PRAM reset. (I have steps on my FAQ page of my 
website if you’re not familiar with that.

Try those and see how you go.
If no success, and seeing you’re up Duncraig way I’d recommend MacWorx 
Joondalup. (Delage Street, Joondalup) - www.macworx.com.au

Hope something there helps.

very puzzled.

Hi there,
I keep receiving a message saying my disc is almost full.  When I go to the
storage section it says only 859mb out of 121 gb is free. 103.77GB is
allocated to system files. This seems excessive. The library folder has
86gb alone. I have deleted a couple of large backup files but not sure what
else to do.
I'm keeping this running Mojave because I'm running Family Tree Builder 32
bit (until the 64 bit one comes out) and Dreamweaver CS6 as for the amount
of use I now get out of it it's not worth asubscription.

MacBook Air (13-inch, 2017)
MacOS Mojave 10.14.6

8 GB 1600 MHz DDR3

iMac random restarts

[Tim Law]

Hello folks.

I have an unhappy iMac (Retina 5K, 27-inch, 2017)
40Gb RAM
10.15.7


Problem is random restarts. 
First symptom is the mouse freezes then about 30 seconds later the computer 
turns off and restarts.  This happens enough to be very annoying, and has 
occurred whilst I was drafting this message. 

The problem first occurred after I had transported the computer, screen down, 
on the seat of my car. No physical external damage is apparent. 


Problem does occur in Safe Boot mode, though not as frequently as in normal 
mode. 

EtreCheck shows nothing out of order
Rebooting into recovery mode and running both Disk Utility and reload latest 
operating system have been done. 

*** MCA Error Report ***
CPU Machine Check Architecture Error Dump (CPU: Intel(R) Core(TM) i5-7500 CPU @ 
3.40GHz, CPUID: 0x906E9)
CATERR detected! No MCA data found.


I had assumed it was a hardware problem triggered by moving the machine but 
nothing is showing up in any errors that I have seen.  I have removed and 
replaced the RAM.   When running, it functions normally as expected. 

Any thoughts on what else I could do before taking it to the doctor?
Which doctor is recommended. 
I live in Duncraig area. 



Thanks
