Opening Unix Executable files on Mac

Hi Ivan, Thanks so much for your reply. After I submitted my question, I went to the file(s) with Finder, right-clicked once on the file, which brought up the picture (yes, just as you were saying - they are pictures) without opening it - and I "copied the image" with Finder, then created a jeg in my faux PhotoShop app Acorn! I just pasted the copy into a new doc - and resized the image, etc., and it's perfect! I haven't tried changing the extension with finder - but it's worth a try! Again, thank you so much for the reply! These are old pictures from one of my sisters' celebration of life that one of her daughters put together - a scrapbook of pictures from her whole life ... very important to me ... and I had never heard of Unix executable files! It's all good!

Hi Ivan, It DOES work to just change the extension .... even though it took me a minute or two to figure out how to "change" the extension .... I finally clicked on the file so I could "rename" (when it turns light blue) and just added .jpg. Then double-clicked and it opened right up. Thank you! Another pair of eyes - a different perspective - really helps!

Now - I have another question that maybe you can answer ... I bought an Apple "Magic Mouse" a year or so ago because my cheapo Logitech was acting up a bit ... and now the Apple mouse drives me crazy because I don't know how much battery I have without going to system preferences, clicking on Mouse, and waiting for the level to come up. OR, it just dies on me, then I can't do anything until I charge it for a few hours, and you can't use while it's charging as you can with an iPhone or iPad ... so annoying. Do you know of anyway to see what the energy level is without going to system preferences? It would be great if there were an icon on the dock to click on ... or something like that ... Maybe it should be called a Mickey Mouse .... (Should I have started a different topic?)

Thanks again, Ivan!

Sorry I "dropped out" for a few days ... my life is crazy ... apt complex has just sold, construction on unit next to my bedroom - and I work nights ... do a lot of editing and writing, working on a sculpture to install 9/10 ... argh.

OK - so leave bluetooth on ... Do you log out, sleep, or shut down when you're not actively working on your mac? I have been logging out lately, on the advice of another mac-nic, but yesterday, I was running late, so put my mini on sleep - about 2 p.m. - and didn't wake it up until 9:30 a.m this morning. It was very weird, didn't want to wake up (neither did I !), a white segmented bar showed up on black screen (with the Apple) - and when it finally came up, my mouse wouldn't work ... I had a class at 10 a.m., so I charged it for a few minutes, and then things worked again - mouse showing 47% battery level. Would bluetooth being on have anything to do with that?

Any particular brand mouse you recommend for a backup? I've used Logitech - works well usually.

ONE MORE THING (thank you for your patience - AND KNOWLEDGE!!) - any tricks for moving files (of any kind) from one place to another, one folder to another, on our wonderful Mac Apples? And can you open a photo in your Photos Library from Pixelmator Pro ... ? Like File>Open>photos>xxx.jpeg? That's TWO THINGS

Thank you, Ivan!!

Once again, Ivan, this is perfect! Thank you, thank you!! (How come the Mac tech didn't know ...?) Now - do I leave Bluetooth on - or turn it off after I check?
