I have only one macro script I need to run on multiple computers. I unfortunately can't share the script themselves.

If by "script" you mean the actual Macro, then it going to be very hard for us to be of much help without seeing the actual Macro. If your Macro contains sensitive and/or proprietary info, perhaps you could change that info in a copy of the Macro, and post the copy here.

Please don't use "script" when you mean "macro", since Macros can contain real scripts (AppleScript, JavaScript, Shell Scripts, etc).

2 seem to get stuck after about 50 cycles of the macro

What do you mean by "stuck"?
Is this Macro called by another Macro in a loop using Execute Macro?
If so, this could be the issue, as KM will not allow more than 50 macro instances to be running at the same time.

See:

Macro stop after a certain number or cycles

The macro will never miss any steps. The macro will be canceled if you have more than 50 simultaneous macros running as described previously - avoiding that is necessary. Other than that, the macro will continue to execute the steps. However the system may process the steps more slowly, and if the system gets behind or goes to sleep, then the steps may not function correctly (eg keys may be lost). To avoid that, you need to ensure you don't allow the system to sleep the screen, screen save t…
