I'm not Ed. And I love OWC. But unless you need an *Intel* Mac for legacy software that will not be re-written in 64-bits or for the Apple Silicon SOCs, I'd avoid all 27" iMacs for now. At some point in the future, Apple will drop support for Intel processors. They are headed down their own path rather rapidly. I expect that 5 years from the introduction of the last Intel Mac, Mac OS will no longer be upgraded for Intel machines.

You get the same hardware and accessories and software, in a white box instead of a colored one. It opens and works just like new. But you save a pretty large handful of change. I bought my MacBook Air from them. I saved about $250.

The M1 Macs are fantastic. The transition has been very smooth for most of us. A few users of obscure software have been frustrated by developers dragging their feet or just dumping Mac support out of hubris. But most Intel Mac software works on the M1 in Rosetta 2 emulation mode.

The wood ducks started showing up here a couple of weeks ago. I always love it when I'm laying low with my camo throw cover over me hoping to capture some photos of them when unexpectedly something else shows up. Last year I had a turtle crawl up next to me, this time I had a little mink run up to me. Camouflage absolutely works.

There is a pair of pileated woodpeckers that are hanging around this same area. I hope I can locate their nesting site and get some baby shots. You know when they're around as they make their loud cries and rainforest sounds.

Captured the first three bird images this afternoon, about 4:50 PM PST. The bird was about 25 feet into the woods, about 65 feet from me and about 15 feet above. Pacific Northwest, just South of Seattle. I believe it to be a Yellow-rumped Warbler. Merlin's example shows a white throat for Myrtle Warblers, and a yellow throat for Audubon's Warbler. Myrtle's Eastern US through Alaska, Audubon's the Western Mountain region. I believe I have photographed a Myrtle's Yellow-rumped Warbler in the PNW! Can anyone help with the ID? I have been wrong too many times...

Caught that Spotted Towhee just as he was jumping off!

American Robin looks majestic in that tree!

That Song Sparrow played Hide and Seek with me until finally flying off.

The White-crowned Sparrow looked regal on that branch.

The Dark-eyed Junco shot required a minimal crop. The rest were over 30 feet away and further.

Very few bees are evident still as it is unseasonably kewl = few flowers.

Download and enjoy!

It sounds like you have enough RAM to run Lightroom. I'm not sure why 16GB wouldn't be enough. I'm using 16GB on an M1 MacBook Air, and I run Lightroom, Photoshop, Mail, Calendar, Calculator, News, Word, Safari, and Epson Scan all at the same time, with no issues. But the M1 manages memory differently from PCs.

Here are the official recommended specifications on Adobe's site for both Lightroom Classic and Lightroom CC:

Computer hardware, including graphics processor? Operating System? Internet Speed?

Many issues with video are related to a lack of system resources, whether slow drive speed, slow Internet speed, full drive, insufficient RAM or VRAM, obsolete operating system, and on and on. Installing an anti-malware package can often require so much processing overhead that working with the machine becomes unbearable. It's a necessary evil, but may result in the need to upgrade or replace the computer. Did you click that button for more information?

Problem not solved, despite all the rhetoric, Macs are also vulnerable to viruses, malware, ransomware, etc. The primary reason you and others believe they’re invulnerable is because they’re such a small percentage of computers in service compared to windows platforms, that they’re not targeted as often. The fact is that Windows Defender is quite competent IF you keep it updated, and all those warning you were getting was Defender doing its job. Most compromised computers are in fact caused by operator error and poor computing practices such as opening infected attachments, single factor authentication and compromised passwords, and a Mac isn’t going to save you from that.

There was a time in the early days of Windows that an external AV application such as Norton was good practice, but those days are over - Windows now includes most of the tools that 3rd party SW used to provide. While there are useful utilities, Norton is serious bloatware. It’s too big, too expensive, has too many extra components (more $), uses too many resources, interferes with too many applications, is very difficult to remove (by design) and unnecessary. Running Norton on every machine is a habit left over from the last century and past it’s value.

For all the bitching about Windows, the fact is that if you have decent computing skills, install Windows correctly, keep it updated, and don’t bog it down with crap like Norton, and keep multiple copies of your data, you’ll encounter very few if any compute problems. Windows 10 runs perfectly on all my machines, I have never had an update issue and have NEVER had a virus or malware attack and I’ve been running Windows since the beginning - a good 30 years. If you prefer the Mac platform/OS, then God bless and carry on, but don’t present it as the answer to everything bad that happens in the compute world or every dumb thing the operator does.

End of rant.
