Adding Transistor Models To LTSpice Library

What is the easiest way to import more transistor models into LTSpice for Mac? I'm just trying it for the first time, and seems like there are no Ge models. I found this long list, but maybe there's a better one..?

Watched a couple videos and my eyes glazed over. I feel like it must be pretty simple...
 
I often add a transistor model using a spice directive directly in the asc file.
I google the model, copy to clipboard, hit .op button, paste model, click ok. Then I change the name of the transistor to the same as in the model.
For example - this is complete model of the 2N5088
.MODEL 2N5088 NPN(IS=5.911f ISE=5.911f ISC=0 XTI=3 BF=1122 BR=1.271 IKF=14.92m IKR=0 XTB=1.5 VAF=62.37 VAR=21.5 VJE=0.65 VJC=0.65 RE=0.15 RC=1.61 RB=10 CJE=4.973p CJC=4.017p XCJC=0.75 FC=0.5 NF=1 NR=1 NE=1.394 NC=2 MJE=0.4146 MJC=0.3174 TF=821.7p TR=4.673n ITF=0.35 VTF=4 XTF=7 EG=1.11 VCEO=35 ICRATING=50m MFG=NSC)

You can also add the model to the appropriate file containing models.
standard.bjt, standard.jft, etc... Open the standard.xxx file with notepad and paste the .model.....

Click to expand...
Thank you!! Adding to the standard.bjt file with Textedit worked! Now to figure out the rest of this pesky program... everything is hidden on the Mac version! Yeesh
