Mojave 10.14.6 all adobe products SLOW, What can I do??

I recently updated to Mojave after LR no longer being able to update (YES! I was quite a few OS versions behind).

After initial BIG issues with Apple and installing the update, I then updated all my adobe CC based programs. I mainly only use PS, LR , Bridge and ACR.

Every single program is either crashing constantly, not loading at all or taking Forever to do anything! It took 6 hours to import 280 photos on Saturday through LR and then crashed. Took another 2 hours to download them via bridge!

Everything since going to CC a few years ago has gradually gotten slower and slower yet we are on Fibre optic NBN internet here in my town in  Australia.

I would really love some help on this issue, as i am a professional photographer and cant be wasting the time I have been to import images....let alone try and edit them (over 2 hours for 2 photos tonight, due to crashing and loading issues).

HELP!!!

Thanks,

Ali
