Void If Removed

Worked for my keep this afternoon, IT Manager’s tech support. Old memory cards removed, new cards added, old cards put back, easy peasy. S booted her Mac back up and voila! .... same memory as before. Hmmm. A quick perusal of the instructions and the advice given was ‘try again’. Fair enough, tried again but putting the cards in different slots, just to add an element of the unknown. And what do you know, new memory recognised, all OK, IT Manager happy. Technology, got to love it.
