Easy Installer is named Beta as it is still in active development. One might spend some time reading this older / historical thread to make a judgement on how wary one should be. [LIST] Devices working with the Easy Installer.
The use of “Drivers” really is a Windows Issue, Update drivers manually in Windows - Microsoft Support. One really has to follow Windows guidance.
Linux users using the documented method have to rely on a flatpack installation (and Easy Installer itself) to get everything right.
I agree Mac users would need some expertise to follow the cryptic clues, but hopefully only if it does not run right first time. Mac however is not renouned for compatibility with other systems !
Windows
It seems that there are often a variety of Windows drivers for some Android devices. Fairphone users have experienced the situation loosely expressed like this; a simple driver might allow communication with the device normally, but not in adb or fastboot – that is three possible connection types. Sometimes the “full” driver might have a name like “combination driver”.
As you prepare to start Easy Installer connect your device to your Windows PC with a good usb data cable and open Windows Device Manager.
In the event your device has a driver issue, Device manager will show it as 
Problem device.
If you see a Problem device run Windows Update, ensure the warning clears.
Without closing Device manager start Easy Installer.
Easy insaller during progress will cycle the device through other modes adb and fastboot [1]. If you see a Problem device in your Device manager window, stop Easy Installer, run Windows Update, ensure the warning clears; continue or restart Easy Installer.
Should Problem device appear at any stage, stop Easy Installer and run Windows Update again.
Remember to restart Windows if it is indicated ! Easy Installer is expected to be competent to “start again” without issue; in this case it will take a litle time to double check any jobs done already.
