Selecting a list of items, mac.

I apologize for probably asking an already answered extremely NOOB question but im new. im trying to select all my cubes at once on my mac and normally you would use shift but that doesnt work here. please help

What mode are you in? If in object mode Shift select seems to work for me. You can use the outliner as well, but you will have to expand each object first, it’s the + button before the object’s description, then cursor down in the expanded list and shift select. At least that it is how it works for me.

currently im in blender render mode. shift and click only selects both the first and last object. none of the ones in between them…

You have to Shift click each one that you want
