Following trials on Lake Michigan USS MACABI (SS-375), on 19 April, entered a floating drydock at Lockport, IL, to transit the Chicago Canal to the Mississippi River, and arrived New Orleans 26 April. Three days later she left for shakedown operations off Panama.

On 3 June, MACABI departed Balboa, Canal Zone, for final training at Pearl Harbor before departing 9 July for the Caroline Islands via Guam, Marianas. She went on lifeguard station off Truk on arriving 21 July. Some 10 days later, MACABI was forced to dive to avoid two aerial bombs off Moen Island.

She returned to Apra Harbor, Guam, for repairs 4 August through 13 August, and was on her way back to Truk when hostilities with Japan were terminated. MACABI was then ordered home, touching Pearl Harbor 27 to 29 August on the way.

Arriving San Francisco 5 September, MACABI entered Mare Island Navy Yard 12 December for inactivation overhaul and decommissioned 16 March 1946. MACABI recommissioned 1 June 1960.
