I recently tested several old MacBooks and as far as I can tell, all
MacBooks that have an ISO keyboard have the tilde key quirk:

Product    Model  Year  System      CPU    Shape  Labels     Country  Quirky
============================================================================
05ac:021b  A1181  2006  MacBook2,1  T5600  ISO    British    13       Yes
05ac:021b  A1181  2007  MacBook2,1  T7200  ISO    Québécois  13       Yes
05ac:0229  A1181  2007  MacBook4,1  T8300  ANSI   Usonian    33       No
05ac:022a  A1181  2007  MacBook4,1  T8100  ISO    English    13       Yes
05ac:022a  A1181  2007  MacBook5,2  P7350  ISO    Québécois  13       Yes
05ac:0237  A1278  2008  MacBook5,1  P7350  ISO    Dutch      13       Yes
05ac:0237  A1278  2009  MacBook5,5  P7550  ISO    British    13       Yes

The model number and year are from the laptop case. Since Apple printed
the same model and year on many different laptops, the system name (as
reported in the SMBIOS tables) and CPU form a more precise identifier.
