You probably have a conflicting installation of a JAR file called "mapleclient.jar". This can happen if you used an older version of MapleNet or Maple TA. To solve this problem, do a Spotlight search for all files called "mapleclient.jar". If you find any such files OUTSIDE of the directory /Library/Frameworks/Maple.framework, try moving them to your Desktop. This should solve your problem. Yu-Hong Wang Senior GUI Developer Maplesoft

Hi Gary, Can you check in Activity Monitor (or "top" from the command line) whether there are any stray processes named "mserver" running after you quit Maple? These are Maple kernel processes, and if one of them became unresponsive then you might see symptoms like those you describe. If you see any running mservers, force quit them and try again. Please let me know if this works, Yu-Hong Wang Senior GUI Developer

Click on the file to open with Maple in the Finder and do a Get Info. Under "Open With...", choose Maple and click on "Change All". This will cause these types of files to open with Maple from now on. Make sure that you are using the correct extension (.mw or .mws) on your filenames. If you still can't open your Windows worksheets, post them here. Yu-Hong Wang Senior GUI Developer

Hi there, I'm a developer and a resident Mac expert at Maplesoft. I'd like to clarify some of the confusion about the state of the Intel version. The summary is, everything that counts in the kernel and GUI is universal. We have a two remaining vestiges of PowerPC code, but they should not impact performance in any significant way. Here's a detailed explanation of what's going on. 1. A PowerPC process (mfsd) shows up when you start Maple. This process is a third-party license manager daemon and is not involved in Maple computations in any way. It won't affect the performance of computations done by the Maple kernel (mserver), which is a universal binary. 2. Maple 10.app shows up as "PowerPC" when you do a Get Info from the Finder. This is because Maple is packaged as a Java app, and such packages contain a launcher application stub (JavaApplicationStub). This is a tiny executable that launches Java and then quits. Unfortunately, we didn't update this stub (oops) with the rest of the update, so we're still using the PowerPC-only version. We'll address this in a future version, but in the meantime rest assured that the worksheet uses the Intel JVM and takes full advantage of Apple's latest and greatest Java technology for the Intel platform. (Read: it's a LOT faster than before!) Because of this remaining PowerPC-only code, you may have noticed that we can't technically use Apple's "Universal" moniker for our product. I'd be happy to answer any other questions you may have about Maple, whether on the Mac, or in general. PLEASE NOTE that there is no download link directly to the Intel Mac installer. You must email support@maplesoft.com with your email address and purchase code to get a download link. This also means that the link from VersionTracker is not the Intel version, so if you downloaded from there, please email us for the actual update. Yu-Hong Wang Senior developer, Maplesoft

I have a working version of that document, which the upload limit on the forum is preventing me from posting. Contact me with an email address and I can send it to you. Yu-Hong Wang Senior GUI Developer
