If you truly mean Remote Access to a machine in the office, that's pretty straight forward. First IN THE OFFICE set up two Macs with QBs. It is strongly recommended that the two machines be on a WIRED network. There are often QB Data issues with WiFi.
You can put the QBs Company file on the main computer with the primary person using QBs. Make sure QBs is in Multi User Mode (under File on the PC and I think the same on the Mac). You then need to SHARE that FOLDER with the second Mac.
On the second Mac, make sure you can reach the QBs folder on the Primary machine. Then launch QBs, confirm Multi User and try to open the file on the Primary machine. (If you don't have a Multi User License, then you'll need a license for the second machine.)
Now that QBs is set, you can Remote into the Second machine and open QBs through that machine. Mac has some options and there are some good 3rd party programs to remote into your office computer.
