I finally bit the bullet and ordered one of these new machines, could arrive by the end of the week: i7/32GB/1TB/V20. I'll try to be brief, but I have a few points I'd like to get some direction on. Background: My last MBP 15" unfortunately was completely Radeon-gated 8 months ago, after suffering the nasty GPU symptoms for about 3 months. This was really annoying, as despite being 7+ years old and the 2.2Ghz model, I had upgraded - RAM to 16GB, 240SSD, 750HDD in Optibay, & Hi-Res Screen....so it was still running like a champ for many things. In May I was offered a new job (I'm a teacher) at a University where all the students have iPads, all the rooms have projectors, and all the lecturers are required to teach using a laptop. Due to being fiscally restrained at that moment, I had to do the unthinkable and pick up a 2nd hand junky windows laptop (US$180) for the short-term until I was able to arrange the sale of a few vital organs to fund the MBP purchase. This 'temp' laptop has been painful on many levels. So, I've got the new i7/V20 on its way. 1st issue: Video Output As I mentioned, a lot of my work involves connecting a laptop to a projector (or sometimes a large monitor / TV screen... 65-70"??) via HDMI or VGA. For some reason my windows laptop can only connect with VGA and you can imagine how fun that is. Obviously my new situation will be working with USB-C and the world of dongles....no dramas there, except which one? After lots of hunting and reading, and bang-for-buck analysis, I started to think about the idea of just using an AppleTV as my 'dongle'. This would actually assist my teaching enormously as I would be able to get the students to stream video directly from their devices which would save lots of time and provide some new opportunities. It would obviously be bigger/heavier etc. than a normal dongle and require power and more $$.....but given the potential benefits I think it's actually justifiable. So, my question is: Would there be any downside I am missing when using an AppleTV as an expensive HDMI dongle? ...in terms of how a laptop talks to a projector vs. how the AppleTV would? Does anyone do this, and if so how is that working out for you? I will still need to get a dongle for USB A / Ethernet and others, but the AppleTV would be my main work dongle and be taken everywhere the laptop goes. 2nd issue: Setup for different users. In the past I have had dedicated work laptops (always cheap Window's POS), so it was easy to separate my work/personal life digitally. Currently, having to use my personal device for work (especially projected in front of up to 200 people) can cause a few dramas... nothing major, just search history and things in google / YouTube etc. which often pop up on the screen when I let the students use my device for the presentations. So, I hope to be able to utilize the Touch ID and even Touch Bar (flame away) to help me better manage things. I figured I would create 2 accounts on the computer - one for personal use and one for work/teaching. I thought the TouchID would be great for this - one finger for each 'user' and away I go. But I have not actually used different users on MacOS since the 90s in high-school, and I don't really know how it works these days (I am guessing it's set up for multiple people as opposed to one individual having multiple accounts?). Would I have problems accessing things from each user, like my iTunes library for example? Could I create shared folders if I needed cross-user access of things occasionally? My question is: Am I thinking about structuring things the right way by creating 2 user accounts on MacOS (each accessed with a different fingerprint) to keep my work/personal life separated? Or will it cause other issues with having to have copies of Apps and iTunes libraries on each users account, for example? I am also hoping to map a lot of nice buttons to the touch bar to help with the things I do at work - nothing major just save a few steps on things I do all day everyday. 3rd issue: Protection On my last MBP I had a cheap Chinese eBay special hard plastic shell. While not everyone's cup of tea, it worked well, was light, and appropriately sacrificial. Given all the talk about throttling and heating/cooling with these new MBPs, I was wondering if anyone would advise against putting anything over the laptop case permanently as it may make the situation worse? My question here is: Has anyone been using a hard/rubber clam shell-like case on the TB MBPs with no problems, or would I be best advised to consider other ways of protecting it? 4th issue: Getting my data from my old laptop I'm pretty sure I still have my old SATA to USB-A cable around somewhere and my little toolkit as well. So, I was planning on ripping the drives out of my old MBP and using the cable to transfer data (approx 100GB on SSD and 700 on HDD) but I guess this would take a while. I have seen some generic USB-C to SATA cables online - would these be ok? I am kind of scared of non-Apple USB-C-anything due to the fact it is relatively new technology and through the TB protocol a lot of power can be carried / potentially do a lot of damage (but I really have no idea what I am talking about here). * I should mention that I don't want to 'clone' my old system or anything, I actually want to start fresh and just copy the old data for backup / data storage So, my question is: Would you guys simply use the USB-A to SATA cable to transfer data or would you get a USB-C to SATA cable instead? And if so, would it have to be an Apple-approved one? I am fairly sure I will be able to get at least a generic one locally. And a couple of other small questions: 1. I have seen a nice little Dell (HDMI/VGA/Ethernet/USB-A) dongle. Is there any reason this wouldn't work properly on a MBP for the jobs I mentioned earlier? Or do the 'Apple / Apple approved' dongles have some secret magic powers that I am not aware of. 2. I would like to have the desktop/background for my work OS display a 'live' view of my calendar in full- or partial-screen mode...is this even possible, any ideas on what I need to be googling? (seems some people just use screenshots). 3. Backing-up: in the past I've been happy to just manually back up, and use a folder system to keep things simple. I am now scared that with the new designs, 'complete' back-ups are absolutely critical. I assume Time Machine is the simplest and easiest (but i've never used it). Are there any other options worth looking into, or is Time Machine just the best system & works effectively? Thanks and any input would be much appreciated!
