Default Sucess, and an observation about Plist

Great stuff: that worked to run chmod.
Perhaps others will have this issue, seems a good idea to add it to the Instructions or FAQ.

Another issue is that I noticed in the MacOSx plist that the OSx version in DTSDKName jumps from 10.9 to 10.14 in Version 296b1.

And yet I'm running 10.13.6, and seem to be able to run the newest versions.

Which is the best version for High Sierra 10.3.6 to run?

Anyways, thanks for the help.

Default too-long iteration times, cured eventually by manual stop all workers/restart all workers

Dual Xeon E5-2670, Windows 7 X64, prime95 V29.8b6, 4 workers, all showed tslower than normal iteration timing, to varying degrees. One example shown following. All 4 exponents are 258M<p<383M. Speed ratios ranged from1.22 to 2.30.

Default Brokien mouse scrolling.

I have set roll wheel one notch to 3 lines, but prime95 does not use these values.

I'm getting the following error (see image) when I run ECM2 on M332XXXXXX. I just ran ECM2 successfully on a much smaller Mersenne.
//EDIT: I don't see the attachment. Here is the screen output:
Opyinizig for CPU architecture: Core i3/it/i7, L2 cache size: 2x256 KB, L3 cache sizw: 3 MB
ECM on M332XXXXXX, curve #1 with s=[digits], B1=50000, B2=5000000.

There is no good reason to run ECM on this exponent. If you are trying to find a factor of it, you are wasting your time now. It is at 81 bits (unless you have a great GPU, don't do any more TF.) You have done P-1 on it. ECM is a waste on this exponent.

I know. I have a laptop that is on for very few hours per year, so I set it to do some factoring on a 100M digit Mersenne on which I am doing PRP on another computer on the tiny off chance I find a factor and save time. I just posted here in case the error is a bug.

Watch the temperature. Laptops do not have the best cooling schemes. I have one Using Prime95, running anything other than small ECM's, it gets really warm. I use the "Throttle=x" setting in prime.txt to control it. Example: Throttle=85 means run 85% and rest 15%. It helps. Prime95 really works a CPU.

Default Undocumented feature to lock GUID?

I seem to remember this being discussed somewhere, but after twenty minutes of flaying around, I can't find it...

Is there a way (with a line in prime.txt or local.txt) to have mprime use the "ComputerGUID=" line as provided in local.txt without changing it (based on changed hardware)?
