Memory card recovery on Mac OS X: Keep in mind, the less you use the memory card you are going to recover your data from, the higher the chance of SD or CF card recover on Mac. Most cameras don't wipe pictures completely from your camera memory card upon deletion or formatting. In most cases, only filenames and file properties are erased, and your photos and video data remain on the memory card until they are overwritten. If you simply erased files on your memory card right from your camera, Disk Drill has a very good chance of recovering them. However, if you took more pictures and saved them to the same card after the initial deletion, you may have overwritten your old data, making it unrecoverable.
You can recover formatted SD card on Mac OS X even if it can't be read by your Mac – if it's shown as having no partitions or logical structure and you get a message saying it requires formatting, try Deep Scan. It will drill down to the data sectors of your memory card on a binary level to search for remaining pictures, music or other recoverable data.
Hi,

The lack of an SD card slot on the 2016 and 2017 MacBook Pro is an inconvenience for photographers of all stripes who shoot with cameras other than the iPhone. The answer—as with everything else. If you still don't have an option, you can have my recommendation here: Wondershare Photo Recovery for Mac, 100% trustworthy software. With this Mac sd card recovery software, you can recover photos, video and audio files from your card in 3 steps, no matter you deleted, formatted or lost your files due to other human or unknown reasons. MacBook Pro models from 2016 and later don't have a built-in SD card slot. You can use a USB-C card reader, or a combination of a USB-C to USB Adapter and a USB card reader. MacBook Air (Mid 2011 and later) Mac mini (Mid 2011 and later) Mac mini (Mid 2010) doesn't support SDXC cards. IMac (Mid 2011 and later) iMac (Mid 2010) don’t support SDXC cards.

If you can't get the Card Reader to work it can be replaced and/or an external card reader is not
expensive.
They do go bad occasionally. Try these :
Setup/Settings (BIOS/CMOS) often F2 as you boot so watch the screen - make sure the USB is enabled.

click Update Drivers (this will likely do nothing as MS is far behind certifying drivers) then Right Click
on it UNINSTALL.
Now move to USB Controllers - Right Click - UNINSTALL everything in the Category one at time EXCEPT
the Category itself - REBOOT. This will refresh the USB driver stack.
Here is the similar procedure in XP, Vista's is the same except we need to clear the specific device if present.

Do the above 1st.
USBDeview is a small utility that lists all USB devices that currently connected to your computer, as
well as all USB devices that you previously used. Run it Options and check the 1st three choices to
see if any are there. You can remove all instances of the drive and then reboot again.

Hi all, 'SeismiGraphix' is a new Multi platform data viewer I developed in Java, as being 100% java code is multi platform, that is can be run in Windows, Linux or Mac Os X and can be use to view formats like Segy, Segd, Seismic Unix and Java Seis. A full featured interactive Java SEGY editor / viewer. SegyTool is a powerful, easy to use tool for viewing all aspects of SEGY data including header displays. Good for a free SEGY viewer though Re: Free SEGY viewer. Sat Sep 04, 2010 12:20 pm. This is indeed a very nice find! Although most professional software also gives some insight in the headers and setup of SEGY files, this is a quicker and more complete way (at least compared to the software I use). Free SEG Y viewer software for Windows Linux Mac. Free SEG Y viewers GSEGYView. SEGY Detective. Link: Radexpro. For Windows and Mac. GPRSoft Viewer. Link: Geoscanners For Windows XP/Vista/7/8. This is intended for displaying GPR data, and it includes SEG Y as one of the formats. Has limited display options. Mac
