To connect to PS Financials on the Hosted platform while using an Apple device, you will need to follow the FAQ: http://faq.scomis.org/kb11320/
Where it has ‘PC Name‘ under step 6 of the FAQ, you will need to enter the following instead of apple.rdp.scomis.org:
Version 2/4 of PS Financials = psf4.rdp.scomis.org
Version 6 of PS Financials = psf6.rdp.scomis.org
The gateway does not need to be changed and can be kept as gw.scomis.org.
