Apple MacIntosh

MAC OS users can run the hotComm Windows clients successfully in Bootcamp, VMWare or Parallels on a Mac OS/X, and the IM-Live Java client can run successfully on Mac OS/X with the latest Apple Java version which can be downloaded from:

TESTING the Java Plugin

Apple has made many changes recently with java and it has presented difficulty for some customers.

We suggest to first test your MAC (and this works on WINDOWS, as well) to see if Java is working properly (which should mean you CAN run the hotComm Super Java if you successfully install the plug-in).

If there are problems with the Java not working, please install java from this site to try and resolve the issue. Note: you will be prompted, and asked if you want to allow the website access for the testing, to install or use java, please be sure to allow and acknowledge those prompts.

Wineskin/hotComm Setup Tutorial Video

** NEW DOC UPLOADED 2018** If you ONLY need hotComm CL (The free version used for events and many trade rooms), please see these instructions: HERE

Download Links - MAC/WINESKIN for ALL MAC OS Including High Sierra

If you're on a MAC using a room that supports the FREE hotComm CL client, and you are fairly good with your MAC, you're welcome to try the appropriate installation above for your room (whether the room allows for the free hotComm CL client OR a subscription based hotComm (Lite or Standard), and follow the instructions HERE for installing hotComm CL on the Open Source Utility tool, "Wineskin". This Document also has information for hotComm Subscription based rooms that require hotComm Lite or hotComm STD.

NOTE: Not all features will be supported as hotComm is a native Windows program. Basic features to attend and participate in a hotComm room will however work, and it is a better alternative than Java. Please see the document and read the section that pertains to the hotComm client that you need (hotComm CL, STD, or hotComm Lite). Once you're finished reading through the instrucions, then perform the install and setup. It takes about fifteen minutes.

NEW DOC - If you ONLY need hotComm CL (free version for Online Trader Central events and many trade rooms), then perhaps you would prefer the shorter version of the document that is available HERE

NOTES: This solution allows a user to run hotComm on their MAC without having to purchase WINDOWS. It makes for a more "robust" trade room experience, as one can then resize the window(s) with the charts or visual graphics (i.e. the hotCam).

Details/System Requirements and full installation instructions are at that link.
