New Software Problem

[ajbarr]

I upgraded to version 1.8 today and am having problems. When I load an image the console makes a very strange display and as I move the mouse over the image I get small trails of squares over the image, then the program crashes. This has happened every time I have opened PixInsight since I installed the new version.

I've attached a screen shot of what I see. I am running an iMac.

Any advice would be appreciated.

Thanks

is this a machine with intel integrated graphics?

I honestly don't know. How can I find out?

so it seems not. juan will have to investigate.

This sounds like it may be a 2009-era iMac with Core 2 Duo processor.

Juan's announcement of 1.8.7 said:

Hardware Requirements: Breaking Changes

The FreeBSD, Linux and macOS versions of PixInsight 1.8.7 require a processor with SSE4.2 instruction support.

The Core 2 Duo predates SSE4.2. According to https://walbourn.github.io/directxmath-sse4-1-and-sse4-2/

SSE 4.1 and SSE4.2 are supported on Intel Core i7 (“Nehalem”), AMD Bulldozer, and later processors.

[pfile]

ah good catch. seemed like a graphics glitch.

ajbarr, can you open Terminal.app and type:

sysctl -i machdep.cpu.features

and see if it says SSE4.1 and SSE.42 somewhere on the line that the program spits out?

rob

p.s.

sysctl -i machdep.cpu.brand_string

will tell you the "friendly name" of the CPU.

[ajbarr]

machdep.cpu.brand_string: Intel(R) Core(TM)2 Duo CPU     E7600  @ 3.06GHz

[pfile]

yeah looks like the machine is too old per john's post.

rob

[pfile]

although, thinking about this more, i'd expect the lack of SSE4.1/4.2 to result in the program terminating with an illegal instruction trap rather than just behaving weird.

So it looks like I would have to buy a new computer to use this version of PI?
