I have been shooting macro for 15+ years. I currently have two different lenses that I work with on my Canon 1D MkII. The first is for studio/indoor use (Canon MP-E 65MM F/2.8 1-5). It can be used outdoors but I don't because you have to get virtually on top of your subject and if the subject moves at all it will sent it out of focus (virtually zero DOF). It is great because it can render a 1-to-1 or up to a 5-to-1 enlargement of your subject. My go-to lens is a Canon EF 180mm f/3.5. It is great outdoors because the long focal length lets you keep some distance from your subject. It will allow you to focus from 1.6' from the film plane to infinity. It will render a 1-to-1 image. I should also note that the F/2.8 and F/3.5 indicates the widest F-stop. The 180MM runs from F/3.5 to F/32 and even at F/32 the DOF on a subject at minimum distance is not much more than a MM or so. I usually set it on F/32 and always use a flash. I also have a 28mm to 135mm telephoto that will allow me to shoot macro but I rarely use the macro function unless it's a last resort. The results aren't that good.
When you shoot macro there is virtually NO DOF. You might expect to get a 1-2mm at most. That is why many macro photographers use focus-stacking to get a greater DOF.
My suggestion would be to rent some different macro lenses that fit your camera, a good tripod, shoot some pics and see for yourself which lens best fits your needs. Everyone has different needs and requirements. It's always best to try it before you buy it. I would suggest that you look for at least a 100mm or greater.
Your MAC OS will do everything you described. You don't even have to upload them to your computer. Just insert the card you captured your photos on into a card reader. The drive should show up in Finder. Just dbl-click on the drive to open it and then dbl-click on the folder containing your photo files. Click on the first file and then click on the "Quick Look" icon in the Finder bar (near the middle of the top bar). This will open up the file for viewing. I have used this on Canon, Sony, and DNG raw files as well JPG and many other file types. You can use the UP & Down arrows to brows through all the files. When you find a file you don't want, just ESC out and drag-and-drop it into the TrashCan. You can continue with "Quick Look" again until you have completed your review. If you want to do more than just review and delete you will need an editor to do that like Photoshop, Light Room, Capture One, Affinity Photo, Luminar, On1 Photo Raw or Photos(Built in MAC OS app). Hope this helps.
You might want to try a product called "T9" by Boshield. The stuff was developed by Boing Aircraft to be used to lube airplane parts. It is designed to withstand extreme changes in temperature, like going from sea level to 70,000+ feet where temperatures are -70 degrees and back down to 120+ degrees. The stuff can be purchased either as a liquid or a spray. You can find it on Amazon. It goes on as a liquid and then dries to a very thin film. Have been using it for years on almost everything. I even use it on my Velbon Micro Slider focusing rail. Had to clean off all the factory grease with a solvent, then let it dry, then sprayed on a small amount of "T9", worked it into rail gearing and rails then let it dry. Have not had to reapply for almost 4 years. Runs smooth as silk.
