Bose SoundLink® Bluetooth® Mobile speaker II not connecting well to mac
I've owned this speaker since it first came out. After updating my macbook pro to OS Catalina 10.15.2 my bose speaker doesn't pair well. I have to turn it on and off multiple times and only sometimes it will connect. I was wanting to update the speaker firmware so went to this page: https://www.bose.co.uk/en_gb/support/article/soundlink_wireless_mobile_download.html
After downloading it and opening it it says the program doesn't work. How can I update the firmware or make it so I can actually connect my speaker again?! I love this speaker and it's still going strong and the only problem is the software it seems now.
Tried doing it on an old laptop too... it downloaded the firmware program and I connected it to the back of the speaker and held down the AUX button but it never flashed or did anything. Thoughts?
