A couple of my students using LTspice on the Mac are having trouble with LTspice either pointing to the wrong library or not finding a library at all.
Here's an example of a simple circuit with an OP 27 - this is one that I netlisted and works as expected.
V3 VA 0 1
R1 Vin VA 68k
R2 0 Vin 68
XU1 Vin 0 N001 N002 Vo OP27
V1 N002 0 -5
V2 N001 0 5
.dc V3 -5 5 1m
.lib ADI.lib
.backanno
.end
The problem is that a couple students are seeing an incorrect .lib statement in their net lists.
For example the exact same schematic for another user generates (i.e. somehow different library
.lib LTC.lib
For another student on also a Mac, the path seems to be broken completely.
Again, this is for using standard parts. The student schematics work fine on my Mac with LTspice.
Any suggestions would be much appreciated!
MFlynn417,
How frustrating! I suspect there's a few different versions of LTspice on everyone's Mac, and maybe even a "broken" install. Let me make some suggestions, and hopefully this will help.…

1) "Uninstall" previous LTspice application and files (I do this in the terminal):
If you have any schematics you want to save, but sure to copy them and move them out of these folders before you blast all of these folders away.
2) Download the latest LTspice install file from www.analog.com/ltspice
3) Install LTspice by executing the downloaded install file and dragging the application into the applications folder.
Based on what you're telling me, I think there are two critical things to ensure:
1) that you are downloading LTspice from analog.com and not elsewhere, and
2) that you are completely removing the contents in all of the directories listed above.
I hope this helps,

thanks Anne for the very fast response - I will ask the student to try this.
Just to follow up - this completely fixed my students problem.
thanks so much!
Excellent!
