Before i tried using Catalina but some of my applications was not compatible with it. so i opted to go downgrade back to mojave. Would you suggest Big Sur now?
Is it safe for me to update my MacBook Air (13-inch, Early 2015) to Big Sur?
MacBook Air 13″, macOS 10.14
If you had apps that weren’t compatible with Catalina, they won’t be compatible with BigSur
Only 64-bit apps do work with Catalina and BigSur.
Which apps do you have that aren’t compatible? Maybe you can update or look for a free alternative.
Also, if you don’t have a printer that works with AirPrint, check on the developer’s website if there is a compatible driver

Tips How to Upgrade to Big Sur
There are several points to consider before attempting the upgrade to Big Sur. The most important is Due Diligence on the part of the User and is a Prerequisite for a smooth upgrade.
The below points should all be consider Before attempting the upgrade.
Point # 1 - There are unconfirmed reports that upgrading from earlier version of macOS will download a " Stub " of Big Sur. This " Stub " maybe about 25 MB is size and is not the Full Installer. If so, run this Application and it should pull down the remainder of Big Sur and commence the Installation
Point # 2 - Are there pre-existing Unresolved Software Issues. They should be resolved prior to upgrading - they may carryover to Big Sur making the system unstable / unusable.
Point # 3 - Are there any AntiVirus, Disk Cleaner, Optimizers, Defrag, VPNs etc installed which should be removed as per Developers Instructions. They are useless, unneeded, cause havoc and interfere with the normal operation of the OS and may even Corrupt the OS requiring a Reinstallation. The Built-in Security of Big Sur is all that is required.
Point # 4 - What are the System Requirements ie: Empty Space Requirements specific to the Big Sur.
Point # 5 - Does the intended computer qualify for the upgrade.
Point # 6 - Are the installed Applications / Extensions compatible with Big Sur. Check with the Developer for compatible Apps / extension or do they offer updates. Same goes for Third Party Drivers for Printer, Scanners etc.
Point # 7 - If upgrading from Mojave and earlier versions of macOS - Remember that Big Sur does not support anything 32 bit. These include Applications, Extensions and Drivers for any devices.
Point # 8 - Do I have a Rescue Plan In-Place. This comprises having a Time Machine Backup and for addition purposes - two Tested Bootable Clones each to separate external drives. This is insurance incase the upgrades goes sideways
Point # 8 - To upgrade to Big Sur will require a quick, stable and reliable Internet Connection - preferred method is via Ethernet Connection. If not available and using Wifi - move computer as close to the Access Point / Router and disconnect all other devices connected to Wifi. Want the maximum bandwidth for the computer being upgraded to Big Sur.
Good Luck and come back to these Forums if there are questions, concerns or comments.
