Establishing a Mac ham shack – Ham with Apple sauce

I am in Australia and got my Foundation License late last year. I have been finding my way and have focused on HF, satellite repeaters on 2/.7, and, more recently, FT8/WSTJ-X. I only have Icom radios (HF/6, 2/.7, receivers, and UHF CB). My Mac is a M2 16/256 MacBook Air and an iPad Pro M4. I have had a few challenges and frustrations around sticking to Mac, logging, and QSL software and platforms.

Sticking to a Mac

Icom doesn’t support Macs, but I overcame this through Parallels. On the Windows side, only Icom-specific software runs (memory management, syncing, and firmware updates).
The biggest issue was getting drivers for the various cables on the Windows side. Mac was no problem, but Windows was a nightmare. Some drivers wouldn’t install to run cables with chips on COM ports. This was overcome by opening the various drivers files in Windows, right-clicking* .inf files in File Explorer, and choosing “install from this location.” It works! I am talking about PL2303,
My Mac software suite is fantastic. My current issue is that only one serial port comes from IC-7300, and I want to use it on SDR Control for Icom, MacLoggerDX, and WSTJ-X. At present, I do a lot of closing and opening. Do you have any suggestions?

Logging and QSL software and platforms

I have decided to use QRZ as my log book and purchased the XML feed with an API to connect into apps. Well, here my nightmare begins. I can’t find an app that syncs up and down with QRZ XML. From what I can gather, most apps will upload to QRZ but not pull down? Why is this the case? What am I missing? Help!
I purchased MacLoggerDX and its iPad app (HD) but can only use the former with rig control if I am not using SDR Control for Icom.
I only want a database like QRZ XML and apps on my Macs, iPhone, and iPad that I can sync both ways.
It would be great if these could link into a QSL service, an issue I find equally challenging. QRZ and eQSL look like they’re from 1995, even though their functionality has been improved. Again, help!
I’ve looked at World Radio League but it gives me the creeps.
This afternoon, I am going to thoroughly read the manuals for SDR Control for Icom and MacLoggerDX to see if I am missing something. WSTJ-X and GridTracker work great with QRZ XML.
Hamrs has potential but only has one way sync (up).
I also have access to a trial of Station Master out of the UK. I am yet to fire it up. Does anyone have experience with this?

Anyway, that’s three months of me having Ham with Apple sauce. Your feedback is welcome.
