Update from Sierra to Mojave - what consider

[RobertoGD]

I'm running Mac OS Sierra 10.12.6 on my MacBook Pro 2017
I'm looking for update to High Sierra or Mojave.
What should I worry about? There is many unstable apps or maybe issues with OS that can make my life worse after update?

I'm using Mac for Web Dev and Design also a lot of photos with iPhone and Camera. I'm using external HDD but formatted to Mac OS file system. This should work without any issue with High Sierra or Mojave and new file system?

Of course first I'll be doing backup but if there is something I should look and worry, pls let me know.

Also few things I'm looking to update is some Adobe apps support and need Xcode.

P.s
Better is to make ex. Update from Sierra to High Sierra and than to Mojave or everything should be ok if I do directly from Sierra to Mojave?

Thanks

I’d recommend a clean reinstall and a straight upgrade to Mojave, since it only takes (for me who often handles fresh Macs) less than 30 mins to setup and you are sure no leftovers (like disabled daemons and configs etc) are carried over.

For your worklod, Mojave has Metal 2, some Metal-enabled photo apps (eg Pixelmator Pro) gain huge speed improvement from this, while those using deprecated OpenGL should not see much performance improvements since Apple deprecated OpenGL and only provides outdated version in Mojave.

If your MBP drive is still HFS+, during the update it’ll be reformatted as APFS, which has copy-on-write capability and so should improve copy speed.

Upgraded our MacBook Pro with no issues. I don't think you have a lot to worry about.
