Thanks for getting back with the device details Olivier!
Sync wallets is something which is on our roadmap, but we’ve never said that’s a possibility today. At current you can see we even have a bit of trouble with bookmarks
The reason why Sync is quite so complex is because we go above and beyond to protect privacy. The materials in the sync storage are blinded to us so it makes some aspects of building and debugging particularly difficult.
Sync as a feature has a mix of specialists who split their time between that and their core platform (Desktop, Android, iOS) so they often juggle priorities. Similarly the Rewards team has a split in obligations as well for per-platform integrations.
As you can see on our about page : https://brave.com/about we’re a bit shy of 100 people. Compare versus other browser orgs and we’re unbelievably productive for the size.
There is literally no other project which has gone from ICO to product in less than 6 months (we did) and we’re now at 6 million users and counting.
Hopefully this can help put a better frame on progress.
To circle back on Brave Rewards and your Macbook. I run Mojave as well and have every build we make for MacOS. I have noticed a handful of people who upgraded from the old Muon browser having some difficulty.
I would suggest thoroughly cleaning out the Brave materials after you have done a proper backup of the data you care about. I’m glad to assist with that!
If you have bookmarks you care about, I would first suggest going to the bookmark manager and exporting those to a file. Please be sure to keep that file in an easy-to-find spot as you’ll need it.
If you have bookmark sync enabled, you could skip that step as long as you have your sync code handy.
If you have any BAT in your browser wallet, click on the gear for your wallet found at brave://rewards/
then follow the backup instructions.
Afterwards, download the latest version of Brave (I would suggest the production version) from brave.com (don’t install it yet)
Next, and this is a bit tricky, you will need to delete the folder located at ~/Library/Application\ Support/BraveSoftware/
Lastly, install the latest version of Brave you just downloaded and import your bookmarks or sync code as well as your wallet info.
From there, you are clear to use Rewards once you enable it.
I realize this is a bit verbose, but I hope it helps!
