Default New to Apple; New to GIMPS

I'm new to Apples, and I'm trying to install the Mac version of the software on my Apple to contribute to the DC process. Yet, after downloading, the is a folder mprime258-MacOSX with mprime in it. What am I missing? I launched mprime that is a terminal session; so what then?

I use launchd to run mprime completely in the background. The setup I use has mprime installed in /Library/mersenne. Put the following into a file called org.mersenne.mprime.plist and place that file in /Library/LaunchDaemons.

<?xml version="1.0" encoding="UTF-8"?>

<plist version="1.0">

Unhappy Same boat

Yes I'm in the same boat (well not new to Macs but new to Gimps) and I'm trying to do it on a G4 PowerPC. It says it can't execut the binaries. Is there an earlier version that would support a non-Intel based Mac?

For a G4 PowerPC you won't be able to run the mprime program. Even so, you can use either the glucas or mlucas programs to do LL tests. You will just have to manually reserve exponents and manually report your results. Also, be prepared for the tests to take a long time; I'm not sure on the figures for this, but I think it might take about 3 times as long for an LL test using mlucas or glucas as it would take using Prime95/mprime.

Although it won't help you on the GIMPS project, phrot runs on PPC. You can find it here. It can be used on other projects, such as Conjectures 'R Us
