I’ve finally managed to update Easy Uploader so that it works on OSX 10.14 and above. Here’s the link. It’s also available on the downloads page.
Please also make sure that you have the latest driver for your FTDI cable installed. They’re available on downloads page or via the FTDI website. There’s also a new Beta version available for OSX 10.15 and above on the FTDI website. I have yet to test this with Easy Uploader. If you have OSX 10.14 and above and try this driver please do get in touch to let me know if it works!
