I presume you are talking about the v10.2 update? Without going to too much immediate effort, can you provide a little more detail on (for example) the time taken to import 10 of your largest images?

Can you confirm you have checked that you have the latest video card drivers as Marianne-Deiters has suggested? And that you have turned off and on your GPU support in Preferences? Regarding the image you have posted, can you provide some details as to its format and pixel size?

I need a little clarification from your post thanks. When you say LR "failed to open my  catalogues" but then the program showed "blank galleries", are you viewing that from inside Lightroom Classic in Grid view? ie: are you actually opening a Catalog but the image thumbnails are blank? ...

Thanks for your post Jacco Can you confirm you have Lightroom Cloud-based (CC) on your desktop computer, and LR Classic on your Laptop?

You appear to tell us in your post that the way you can tell if LR has started is because it appears in the Task Manager. Please have a look through some of the information in this link  https://community.adobe.com/t5/Get-Started/Questions-you-need-to-answer-to-receive-better-help/td-p/... and post at least your OS and Lightroom version numbers thanks.

Tony that's not what you'd expect from this relatively simple process. Can you detail your in-camera HDR settings so we can better understand whats involved there from your hardware?

If I read you correctly, your Mac OS was reinstalled and a copy of Lightroom came with that installation?

Responding to Part 2: As far as I am aware, if you use the same card to Import from (with some photos added later), Lightroom will recognise that and gray out the already imported images for you. As far as this goes: What's the difference between setting the Lens Profile pane option called "Setup" between Default and Auto? Please post a screenshot. ... View more

Can you test this? If you have the NAS folder present and able in Lightroom, with the identical folder structure, and you are getting the "missing image" icon in the Grid View thumbnail, that you can click on that and it should find all "missing" image files in one hit. Screenshot please! ... View more

I believe your issue is moderately complicated (and I'm sure frustrating), but can you cut Apple Photos out of the workflow? I'm wondering what Apple Photos does for you in the big picture? It seems to me that if this is breaking the LR Map module for you that you could transfer directly to LR first and then add to Apple Photos. Would that work? ... View more

I'm not sure of your LR version (or even whether this bug applies to your case), but it could be so. Here's something from the recent part which may help. It's a recently introduced bug. Please add details of your issue to this bug report: Lightroom: HEIC photos import with Metadata Status: Changed On Disk | Photoshop Family Customer Community  Are you importing HEIC photos from an Iphone, and observing Metadata Status: Changed On Disk?  If so, that bug was fixed a year ago in LR 8.4. Do the menu command Help > System Info and verify you have the latest version of LR (9.4). "I highlighted twenty of the "metadata conflict" images and the recommended "fix" only took care of the first one - the other nineteen had to be done individually." Most likely, you are in Loupe view in Library or Develop (just one photo showing). In Loupe view, many commands only operate on the most selected photo, not all the photos you selected in the filmstrip. Do the menu command View > Grid to go to grid view and then do Metadata > Save Metadata To File -- the command will apply to all the selected photos.   Can you see the Metadata conflict icon on any of your thumbnails? ...

Are we talking about LR Classic or more of an anticipated problem in LRCC? Have you got that new drive in your LRC folder view yet?

I am probably not the person who can answer you need for "xmp" clarification; there are others including John Rellis who might be more able. Below in quotes is some advice from him "Lightroom Classic does not organise presets in physical folders anymore. You can organise them in groups in the presets panel like before, but you do that by using the 'Manage Presets' option within Lightroom. If you want the old behavior back, look at this plugin: http://www.johnrellis.com/lightroom/fixpresets.htm"   However Ahmed,  I thought the dng approach might give you an outcome that may work and yet be simpler to implement. Some of the below applies to LR Cloud which may or may not be relevant to you.   First- Presets for Lightroom (Classic and Cloudy) are always XMP files. The reason for DNG would be for people with the 'free' version of Lightroom on their phones or ipads.   The DNG file is  a raw image filetype that can have preset edits embedded within the file. The DNG file acts as a "Carrier" (like the Trojan Horse!).  Lightroom-Classic users would 'Export as Original DNG' after saving the editing metadata to the file. The DNG file is now imported into Lightroom-"free" and the embedded Preset can be extracted from the DNG. https://stayclosetravelfar.com/how-to-install-lightroom-mobile-presets/   Anyone with a subscription to the Photography Plan with Lightroom, can easily have XMP Presets Imported into Lightroom-Desktop (ie. Lightroom-Desktop on a PC/Mac) and the Presets will automatically sync to mobile devices. 'Carrier' DNGs are NOT required. https://helpx.adobe.com/in/lightroom-cc/using/add-sync-mobile-presets.html   Otherwise the other forum might shed some light on this for you. All the best Ahmed. ...
